    uh, well, we need to start over since you missed something important in the beginning of the problem

    your equation is 7x^2-6x = -2 we need to add 2 to both sides first, to get 0 on the right side 7x^2 - 6x + 2 = 0 giving us: a = 7, b = -6, c = 2 (not -2)

    also, you made a small mistake in the quadratic formula: |dw:1440032890263:dw| (you missed the b^2 part)

    anyway, after we plug in a, b, and c we get: |dw:1440032970739:dw|

    |dw:1440033237890:dw| now, if you haven't learned about imaginary numbers, we would put "no solution" as our answer since the square root of -20 is an imaginary number. otherwise, we can keep going

    then divide everything by 2, giving us: |dw:1440033419750:dw| which ends up being our answer, if we are considering imaginary numbers
