    I think it's A, but my mom thinks it's B, so I'm not 100% sure.

    I know the formula for the quadratic equation, but I wasn't 100% sure cause B is a negative. So it really should look like -(-5) not -5

    -(-5)=5

    My mom thought it was B, because once you simplify -(-5), it becomes positive. But I know that you simplify the radicand before you do anything else, so I wasn't sure if it was A or B.

    a = 2, b = -5, c = 18 take the opposite of the value of b to go from -5 to +5 so choice B is the only one that fits that has +5 as the first thing in the numerator
