B:4

C:0

Layne Key · Answer 2

(8x^2) + 4x=0

you would use quadratic formula which is - b + / - square root ((b^2) - 4ac) / 2a

a: 8

b: 4

c: 0

-4 + / - square root ((4^2) - 4 (8) (0)) / 2 (8)

(-4 + square root 16) / 16 = 0

(-4 - square root 16) / 16 = - 0.5

the two solutions are 0 and - 0.5
