Answer 10

so the answer is 64 or -64? can you tell me how you got that answer?

Answer 11

x^2 - 16x
we have to complete the square
we'll take -16
(-16/2)^2
= 64
we'll add and subtract 64 in the eq
x^2 - 16x - 64 + 64
now since we know
(x)^2 + 2 (1)(-8) + (-8)^2 + 64
(x-8)^2 +64
so -64 is your answer
