Question

Factor completely. n 2 + 7n - 44 (n - 4)(n - 11) (n - 4)(n + 11) (n + 4)(n - 11)

Answer 1

The answer is (n+11)(n-4). You want to find what multiplies to make -44 and what adds to make 7.

Answer 2

The answer is n = 11, 4, and -4 because factor n2 + 7n -44 and you get 11 and -4 but the rest you distribute and get n2-15n+44 and the zeros are n = 11 and 4
