To find the difference in the perimeters of the rectangles, we need to find the perimeters of each rectangle first.
The area of a rectangle is given by the formula: Area = Length * Width.
Let's assume the dimensions of the larger rectangle are l and w, and the dimensions of the smaller rectangle are L and W.
So, we have two equations:
l * w = 6x^2 + 5x + 1, and
L * W = x^2 - 25.
The perimeter of a rectangle is given by the formula: Perimeter = 2 * (Length + Width).
For the larger rectangle, its length is l and its width is w, so its perimeter is:
P1 = 2 * (l + w).
Similarly, for the smaller rectangle, its length is L and its width is W, so its perimeter is:
P2 = 2 * (L + W).
Let's solve for l and w in terms of x from the first equation:
l * w = 6x^2 + 5x + 1.
We can use the quadratic formula to find the dimensions:
l = (−b ± √(b^2 - 4ac)) / 2a, where a=1, b=5, and c=1.
l = (−5 ± √(5^2 - 4*1*(1))) / (2*1)
l = (-5 ± √(25 - 4)) / 2
l = (-5 ± √21) / 2
Similarly, solving for w, we get:
w = (-5 ± √21) / 2.
For the smaller rectangle, we have:
L * W = x^2 - 25.
We don't have enough information to find the exact dimensions L and W, so let's assume some values.
Let's assume L = x + a and W = x + b, where a and b could be any real numbers.
The perimeter P1 is given by:
P1 = 2 * (l + w) = 2 * (−5 ± √21) / 2 + (-5 ± √21) / 2 = -5 ± √21 - 5 ± √21 = -10 ± 2√21.
The perimeter P2 is given by:
P2 = 2 * (L + W) = 2 * (x + a + x + b) = 2 * (2x + a + b).
So, the difference in the perimeters of the rectangles is:
P1 - P2 = (-10 + 2√21) - 2 * (2x + a + b) = -10 + 2√21 - 4x - 2a - 2b.

The perimeter P2 is given by:
P2 = 2 * (L + W) = 2 * (x + a + x + b) = 2 * (2x + a + b).
So, the difference in the perimeters of the rectangles is:
P1 - P2 = (-10 + 2√21) - 2 * (2x + a + b) = -10 + 2√21 - 4x - 2a - 2b.

I apologize for the confusion in my previous response. Let's reevaluate the problem:
The area of the larger rectangle is expressed as 6x^2 + 5x + 1, and the area of the smaller rectangle is expressed as x^2 - 25.
The formula for the area of a rectangle is: Area = Length * Width.
For the larger rectangle, the area is given as 6x^2 + 5x + 1. We can assume the length is 6x and the width is (5x + 1). Therefore, the perimeter of the larger rectangle would be:
Perimeter1 = 2 * (Length + Width) = 2 * (6x + 5x + 1) = 2 * (11x + 1)
For the smaller rectangle, the area is given as x^2 - 25. Let's assume the length is x + 5 and the width is x - 5. Therefore, the perimeter of the smaller rectangle would be:
Perimeter2 = 2 * (Length + Width) = 2 * (x + 5 + x - 5) = 2 * (2x)
The difference in the perimeters of the rectangles would be:
Perimeter1 - Perimeter2 = [2 * (11x + 1)] - [2 * (2x)] = 22x + 2 - 4x = 18x + 2
So, the difference in the perimeters of the rectangles is 18x + 2.
The area of the larger rectangle is expressed as 6x^2 + 5x + 1, and the area of the smaller rectangle is expressed as x^2 - 25.
The formula for the area of a rectangle is: Area = Length * Width.
For the larger rectangle, the area is given as 6x^2 + 5x + 1. We can assume the length is 6x and the width is (5x + 1). Therefore, the perimeter of the larger rectangle would be:
Perimeter1 = 2 * (Length + Width) = 2 * (6x + 5x + 1) = 2 * (11x + 1)
For the smaller rectangle, the area is given as x^2 - 25. Let's assume the length is x + 5 and the width is x - 5. Therefore, the perimeter of the smaller rectangle would be:
Perimeter2 = 2 * (Length + Width) = 2 * (x + 5 + x - 5) = 2 * (2x)
The difference in the perimeters of the rectangles would be:
Perimeter1 - Perimeter2 = [2 * (11x + 1)] - [2 * (2x)] = 22x + 2 - 4x = 18x + 2
So, the difference in the perimeters of the rectangles is 18x + 2.

I apologize for the incorrect response. Let's reevaluate the problem again.
The area of the larger rectangle is expressed as 6x^2 + 5x + 1, and the area of the smaller rectangle is expressed as x^2 - 25.
The formula for the area of a rectangle is: Area = Length * Width.
For the larger rectangle, the area is given as 6x^2 + 5x + 1. We can assume the length is (3x + 1) and the width is (2x + 1). Therefore, the perimeter of the larger rectangle would be:
Perimeter1 = 2 * (Length + Width) = 2 * [(3x + 1) + (2x + 1)] = 2 * (5x + 2)
For the smaller rectangle, the area is given as x^2 - 25. We can assume the length is (x + 5) and the width is (x - 5). Therefore, the perimeter of the smaller rectangle would be:
Perimeter2 = 2 * (Length + Width) = 2 * [(x + 5) + (x - 5)] = 2 * (2x) = 4x
The difference in the perimeters of the rectangles would be:
Perimeter1 - Perimeter2 = [2 * (5x + 2)] - [4x] = 10x + 4 - 4x = 6x + 4
So, the difference in the perimeters of the rectangles is 6x + 4.
The area of the larger rectangle is expressed as 6x^2 + 5x + 1, and the area of the smaller rectangle is expressed as x^2 - 25.
The formula for the area of a rectangle is: Area = Length * Width.
For the larger rectangle, the area is given as 6x^2 + 5x + 1. We can assume the length is (3x + 1) and the width is (2x + 1). Therefore, the perimeter of the larger rectangle would be:
Perimeter1 = 2 * (Length + Width) = 2 * [(3x + 1) + (2x + 1)] = 2 * (5x + 2)
For the smaller rectangle, the area is given as x^2 - 25. We can assume the length is (x + 5) and the width is (x - 5). Therefore, the perimeter of the smaller rectangle would be:
Perimeter2 = 2 * (Length + Width) = 2 * [(x + 5) + (x - 5)] = 2 * (2x) = 4x
The difference in the perimeters of the rectangles would be:
Perimeter1 - Perimeter2 = [2 * (5x + 2)] - [4x] = 10x + 4 - 4x = 6x + 4
So, the difference in the perimeters of the rectangles is 6x + 4.
