You can't FOIL it so you have to use the quadratic formula..

-b+square root of b^2 -4ac all divided by 2a and -b+square root of b^2 +4ac all divided by 2a

4. anonymous

oops sorry for the second one -b-square root of b^2 -4ac all divided by 2a

5. anonymous

-b+square root of b^2 -4ac all divided by 2a and -b-square root of b^2 -4ac all divided by 2a

6. anonymous

$(-b \pm \sqrt{b ^{2}}-4ac\2a)$

7. anonymous

sq root goes across to the 4ac

9. anonymous
