Question

Solve using the quadratic formula x^2-7x-6=0

Answer 1

Compare your quadratic equation with \(ax^2+bx+c=0\)
find \[a=...?\\b=...?\\c=...?\\\] \[ \\ \sqrt{b^2-4ac}=...?\]
then the two roots of x are:
\(\huge{x_{1,2}=\frac{-b \pm \sqrt{b^2-4ac}}{2a}}\)

Answer 2

I did that part.

Answer 3

show us whatever you have got.

Answer 4

and i simplified it and now im stuck on
