Answer:

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
