Answer 2

just plug it in to the quadratic formula so easy

Answer 3

do u know the formula?

Answer 4

quadratic formula: \(x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\)

Answer 5

I need a step by step run through so i can see it for myself please & ty

Answer 6

Your equation: \(2x^2-8x=-7\) where \(a=2~,~b=-8~,~ c=+7\)

Answer 7

why dont u try it first and we'll correct you along the way

Answer 8

help

Answer 9

I'm more of a visual learner ;)

Answer 10

Ok nvm, would my final answer be -5 +- sqrt 17 / 2

Answer 11

\[2x^2-8x=-7\]\[2x^2-8x+7=0\]\[\text{quadratic equation form}:~ \color{blue}{a}x^2+\color{red}{b}x+\color{orange}{c}=0\]\[\text{your equation}: ~ \color{blue}{2}x^2\color{red}{-8}x+\color{orange}{7}=0\]\[\text{quadratic formula} : ~x = \frac{-b\pm \sqrt{b^2-4ac}}{2a}\]\[\text{values}: ~ a=2~,~ b=-8~,~ c=7\]
