The legs of an isosceles triangle measures 2x^4+2x-1 units. The perimeter of the triangle is 5x^4-2x^3+x-3 units. Write a polynomial that represents the measure of the base of the triangle.

the answer is 46
I don't know how you actually found a value :/
2x^4 + 2x -1 add 2x^4 + 2x-1 because these are two legs of the triangle.
4x^4 + 4x -2
Now subtract this from the perimeter to get the length of the base. Actually with signed numbers, we don't subtract, we add the opposite.
5x^4-2x^3 + x - 3
+ -4x^4 -4x +2
x^4 -2x^3 -3x -1 This is the answer.
It is not possible to come up with a 46
4x^4 + 4x -2

x^4 -2x^3 -3x -1 This is the answer.
