Question

HELP, WILL REWARD!
What value completes the square for the expression?
x^2-16x

a.-64
b.64
c.32
d.-32

Answer 1

b because what u wanna do is always take the b term in ax^2+bx+c and divide that by two and square it. so in this case, half of -16 is -8 and when squared it would become positive right? -8*-8 = 64 cheers :)
