Question

Can someone help me solve this problem by factoring. x^2 + 8x + 16 = 0

Answer 1

Factorization: (x + 4)∧2=0

Solutions based on Factorization: x + 4 = 0  ⇒ X∨1 = X∨2 = -4

Answer 2

The last number factors are 1*16, 2*8, 4*4
Of these factor pairs, which ones add to the center terms (8)?
4*4 = 16 and 4+4= 8
The factors are (x + 4) (x + 4)
