A. (x+12)(x-12)
B. (x-12)(x-12)
C. (x+12)(x +12) D. (X)(x-144)

Answer 1

What are the factors of x2 – 144?

✔ (x – 12)

and

✔ (x + 12)

Explanation:

Answer 2

A. (x+12)(x-12)

Explanation:

Use foil method

x * x = x^2

x * - 12 = - 12x

12 * x = 12 x

12 * - 12 = - 144

x^2 [- 12x + 12x= 0x = 0] - 144

x^2 + 0 - 144 =

x^2 - 144 #
