The quadratic formula is a lifesaver when factoring isn’t obvious! Remember, if you find a negative number under the square root while using the formula, it means your solutions involve imaginary numbers. But for this problem, we’re lucky since the discriminant (
) is positive, giving us two distinct real solutions:
and
. Happy calculating!
