Question

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

Answer 1

Explanation:

x2 + 3x - 4

First we will multiply 4 by 1 = 4 factors of 4 are 1 and 4 so

x2 + 4x - x - 4

x (x + 4) - 1( x + 4)

(x + 4) and (x - 1) are the factors
