What are you looking for? Vertex? Point on the parabola? Intercept?

hero · Answer

3x^2+9x-12 = 0
3x^2-3x+12x-12=0
3x(x-1)-12(x-1)=0
(x-1)(3x-12)=0
x=-4,1

Oh those aren't coordinates, they're solution sets. Well still, I can't really graph it for you, but I can factor it.
3(x^2+3x-4)
3(x+4)(x-1)
x=-4,1
