Use the quadratic formula to solve the equation x^2-7x-6=0

Explanation:

We have been given with the quadratic equation

We have general formula to find the roots of a quadratic equation first we find the discriminant with formula

and after that to find the variable suppose x we have the formula

And general quadratic equation is

On comparing the given quadratic equation with genral quadratic equation we will have values

a=1, b=-7 and c=-6

After substituting these values in the formula we will get  

After substituting in the formula to find x we will get

m
