Question

Which of the following is a solution to the quadratic equation 4x2+2x=10? Assume that the solution has been rounded to the nearest hundredth, if applicable.(1 point)Responsesx=1.15x equals 1.15x=−1.85x equals negative 1.85x=−0.77x equals negative 0.77x=1.04

Answer 1

Solve 4x^2 + 2x - 10 = 0 → x = [-2 ± sqrt(4 + 160)]/(8) = [-2 ± sqrt(164)]/8 = [-1 ± sqrt(41)]/4 ≈ 1.3508 or -1.8508.
Rounded to the nearest hundredth, the solution given is x = -1.85.
