Ramiya is using the quadratic formula to solve a quadratic equation. Her equation is x = StartFraction negative 3 plus or minus StartRoot 3 squared minus 4(1)(2) EndRoot Over 2(1) EndFraction after substituting the values of a, b, and c into the formula. Which is Ramiya’s quadratic equation?

Quadratic formula: x = StartFraction negative b plus or minus StartRoot b squared minus 4 a c EndRoot Over 2 a EndFraction

0 = x2 + 3x + 2
0 = x2 – 3x + 2
0 = 2x2 + 3x + 1
0 = 2x2 – 3x + 1

0 = x^2 + 3x + 2

Reason: In the formula -b = -3 so b = 3, 2a = 2(1) so a = 1, and the discriminant uses c = 2. That gives 0 = 1x^2 + 3x + 2.
