Question

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

Answer 1

First move all terms to one side: 2x^2 − 4x − 3 − 3 = 0 ⇒ 2x^2 − 4x − 6 = 0.
Divide by 2: x^2 − 2x − 3 = 0.
Quadratic formula: x = [2 ± sqrt(4 + 12)]/2 = [2 ± 4]/2.
Thus x = −1 or x = 3.

Smaller solution first: −1, 3.
