one x intercept for a parabola is at the point (-0.33 ,0) use the quadratic formula to find the other x intercept for the parabola defined by this equation: y--3x^2+5x+2

OpenStudy (tkhunny):

Well, do it. x-intercepts correspond to y = 0. Make the substitution and solve.

OpenStudy (anonymous):

how will this get solved? is y=3x... or y=-3x....?

OpenStudy (tkhunny):

y = -3x^2 + 5x + 2 x-intercepts are y = 0. Substitute. 0 = -3x^2 + 5x + 2 Factoring, Quadratic Formula, Completing the Square - Take your pick.
