Please factor it with steps, thanks!

I have the answer, just not the steps. Can you give me the steps Electric?

I just did it in my head....but you can (again) use the Quadratic formula to fin the values of x

x=b±b24ac2a

 

x=1±124(1)(2)2(1)   x = -1/2 +- (sqrt9)/2  = -1/2+- 3/2  =  -2 or 1

 

so the roots are -2 or 1      x+2   or  x-1     so     (x+2)(x-1)=0   results in x=-2 or 1
