Question

How do you solve `x(x+6)=-2` using the quadratic formula?

Answer 1

`x(x+6)=-2 , x^2+6x+2=0,a=1,b=6,c=2`
`x=(-6+-sqrt(6^2-4(1)(2)))/2=(-6+-sqrt(28))/2=(-6+-4sqrt7)/2`
`x=-3+-2sqrt7`

Explanation:

First distribute the x into x+6 and then put everything on one side then use the quadratic formula to solve for x.
