Question

Which expression correctly factors the polynomial?

x² – 36
A. (x - 6)^2
B. (X-6)(x+6)
C. (x-9)(x+4)
D. x(x - 36)

Answer 1

the answer is A
have a great day!

Answer 2

B

Explanation:

(x-6)(x+6)

1. x * x = x^2
2. -6 * x = -6x
3. 6 * x = 6x
4. -6 * 6 = -36
5. x^2 + 6x - 6x -36

The -6x cancels out the other 6x

x^2 - 36
