Question

What is x2 − 5x − 7 = 0 plugged into the quadratic formula?

Answer 1

\[\frac{ -b \pm \sqrt{b^2-4(a)(c)} }{ 2a }\]

Answer 2

I think ax2 + bx + c = 0. ?

Answer 3

A B C
1x^2 - 5x -7 = 0

Answer 4

yes

if given the form

\[ax^2+bx+c=0\]
then the quadratic equation is

\[x= \frac{ -b \pm \sqrt{b^2-4ac}}{2a}\]

Answer 5

\[\frac{ 5\pm \sqrt{(-5)^2-4(1)(-7)} }{ 2 }\]
