It should not be 3x2=x-2=0 ?

either 3x2+x-2=0 or 3x2-x-2=0?

3x2+x-2=0 

Jun 18th, 2015

3x^2+x-2=0

3x^2+3x-2x-2=0

3x(x+1)-2(x+1) =0

(3x-2) (x+1) =0

x = 2/3 or -1

So sum of the solutions = 2/3 + -1

                                          = -1/3

Please let me know if you have any questions and best me if you are satisfactory.
