    okay :) You have to use the quadratic formula for this: |dw:1434291441022:dw| From your equation, can you tell me what's a, b and c? Then plug it into the formula :)!

    in the formula why is b squared 3 and not -3 @butterflydreamer

    b squared? We know b = -3, so b^2 = -3 * -3 = 9 (multiplying two negatives make a positive)

    oh yeah, it should be (-3)^2 :) But -3 squared and 3 squared both give you 9... just a typo probably
