Question

The factorization of x2 + 3x – 4 is modeled with algebra tiles. What are the factors of x2 + 3x – 4? A) (x + 4) and (x – 4) B) (x + 3) and (x – 4) C) ( x + 4) and (x – 1) D) (x + 3) and (x – 1)

Answer 1

C: (x + 4)(x - 1)

Explanation:

Please use " ^ " to indicate exponentiation. Thanks.

x2 + 3x – 4 → x^2 + 3x - 4 = (x + 4)(x - 1) This matches Answer C.
