if so..its a parabola...Let y = 0 and solve for x...then once you get your two factors, you plug in those numbers into your parabola and that would give you the y for both points...then thats your answer

factor your expression and set to zero: 2x^2 + x 15 = 0 (2x  5)(x + 3) = 0 solve for x and that's where your graph crosses the x axis.
