Multiply (x - 4) (x+2)

Answer 1

To multiply (x - 4) and (x + 2), you can use the distributive property:

(x - 4)(x + 2)
= x(x) + x(2) - 4(x) - 4(2)
= x^2 + 2x - 4x - 8
= x^2 - 2x - 8

Therefore, (x - 4)(x + 2) = x^2 - 2x - 8.

Answer 2

Greatest common factor of 2x² and 4x²y?

Answer 3

To find the greatest common factor of 2x² and 4x²y, we need to factor out the greatest common factor from both terms.

Both 2x² and 4x²y have x² as a common factor. However, 2 and 4 are also common factors but 4 is the greatest common factor as it can be divided evenly into both numbers.

So, the greatest common factor of 2x² and 4x²y is 4x².

Answer 4

Rewrite 6x + 18x² by factoring out GCF

Answer 5

To factor out the greatest common factor (GCF) of 6x and 18x², we first need to identify the GCF of both terms.

The GCF of 6x and 18x² is 6x because it is the highest number that divides evenly into both terms.

Now, rewrite 6x + 18x² by factoring out the GCF which is 6x:

6x + 18x² = 6x(1 + 3x)

Therefore, 6x + 18x² can be rewritten as 6x(1 + 3x) after factoring out the greatest common factor.

Answer 6

7(4x - 15) =63 solve

Answer 7

To simplify and solve the equation 7(4x - 15) = 63, you need to first distribute the 7 on the left side of the equation:

7(4x - 15) = 7*4x - 7*15
28x - 105 = 63

Now, add 105 to both sides of the equation to isolate the variable term:

28x - 105 + 105 = 63 + 105
28x = 168

Next, divide by 28 on both sides to solve for x:

28x / 28 = 168 / 28
x = 6

Therefore, the solution to the equation 7(4x - 15) = 63 is x = 6.
