Question

Factor 64 - x2. a. (8 - x)(8 - x) b. (8 + x)(8 - x) c. (x + 8)(x - 8)

Answer 1

The function 64 - x2 can be patterned from the special factoring (a2 - b2) where the factors of the terms are equal to (a + b) ( a - b). In this case, as we follow, 64 - x2 is equal to (8 - x) * (8 + x). Hence answer to this problem should be B

Answer 2

$Use:a^2-b^2=(a-b)(a+b)\\\\64-x^2=8^2-x^2=(8-x)(8+x)$

Answer: 64 - x² = (8 - x)(8 + x)
