Question

Solve 2x^2+−4x−3=3 using the quadratic formula. Enter the smaller solution first.(1 point)

Answer 1

First put in standard form: 2x^2 − 4x − 3 = 3 → 2x^2 − 4x − 6 = 0 → x^2 − 2x − 3 = 0.

Using the quadratic formula (a=1, b=−2, c=−3):
x = [2 ± sqrt(4 + 12)]/2 = [2 ± 4]/2 → x = 3 or x = −1.

Smaller solution first: −1, 3
