Ax4 + bx2 + c=0 (a>0) (c>0) The quadratic equation has two solutions If
1)b2>4ac
2) b2-4ac>0

1) is right

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x

unlimited solutions.

if i put something wrong your not gonna like it so rather not say nothing.
