Verified answer

--------------------------------------------------

x²+32x+256=0

=> (x+16)(x+16) = 0

=> (x+16)² = 0

=> x = -16

Hope This Helps !

This can be factored as (x+16)^2 = 0 (from inspection)

If you are ever in doubt, you could always use the quadratic formula to solve for x

So, solution is x= -16

by factorization, we get

x^2+16x +16x +256

x(x+16)+16(x+16)....this gives

(x+16)(x+16) are the factors of the expression

when

(x+16)(x+16)=0.......it means

x=-16 twice

I think Math's PHD's answer is correct.
