Question

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

Answer 1

First move 3: 2x^2 − 4x − 6 = 0. Divide by 2: x^2 − 2x − 3 = 0.
Using the quadratic formula (or factoring): x = [2 ± sqrt(4 + 12)]/2 = [2 ± 4]/2.
So x = -1 or x = 3.

Smaller solution first: -1, 3.
