Icould really use some with this question.

Parabolas y=−2x^2 and y=2x^2 +k intersect at points a and b that are in the third and the fourth quadrants respectively. find k if length of the segment ab is 5.

Solve each quadratic equation by factoring and using the zero product property. 10x + 6 = -2x^2 -2
