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

A is the correct answer on edge

Answer 2

`x^(2) +3x+2=0`

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`
