Applying the quadratic formula to 4x² + 4x − 3 = 0 gives x = (−4 ± 8)/8. Written in lowest terms, the roots are:

Question

Accepted Answer

1/2 and -3/2. D = 16 + 48 = 64, so the working is right: x = -4 + 8/8 = 4/8 = 1/2 and x = -4 - 8/8 = -12/8 = -3/2. Check: 4 × 1/4 + 2 - 3 = 0 and 4 × 9/4 - 6 - 3 = 0. Dividing −12 by 4 instead of 8 gives the wrong −3.

Applying the quadratic formula to $4 x^{2} + 4 x - 3 = 0$ gives $x$ = (−4 ± 8)/8. Written in lowest terms, the roots are:
