Remove the common factor first; after that, it will be easy to factor.

Answer 2

you might have to use the - b formula

Answer 3

im sorry, its completing the square

Answer 4

Completing the square:

\[2x^2+2x-6=0\]\[x^2+x=3\]\[x^2+x+1/4=3+1/4\]\[(x+1/2)^2=13/4\]\[x+1/2=\pm \sqrt{13}/2\]\[x=-1/2 \pm \sqrt{13}/2\]

Answer 5

I guess it wouldn't have factored that well.....

Answer 6

thanks, i have another one if you don't mind 3x^2+6x-5=0
