    quadratic formula is \[\large y = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}\] do you know which is a, b and c in your problem?

    so, i plugged in the numbers and I got 7+- the square root of 53 over 2...I do not think that is right.

    Go back and recheck your formula. You probably forgot to attach your negative sign to b.
