Multiply (x−4)(x+2) .

Answer 1

To multiply (x−4)(x+2), we 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, the product of (x−4)(x+2) is x^2 - 2x - 8.

Answer 2

What is the greatest common factor of 2x2 and 4x2y ?

Answer 3

To find the greatest common factor of 2x^2 and 4x^2y, we need to identify the factors that both terms share.

First, let's factor each term:

2x^2 = 2 * x * x
4x^2y = 4 * x * x * y

Now, we can see that the common factors in both terms are 2, x, and x. So, the greatest common factor of 2x^2 and 4x^2y is 2x^2.
