Question

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

Answer 1

Answer:

$x^{2} +3x+2=0$

Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form $ax^{2} +bx+c=0$ is equal to

$x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$a=1\\b=3\\c=2$

therefore

The quadratic equation is

$x^{2} +3x+2=0$
