1)y=x²3x+2
2)y=8x16/x3
A)Sketch both on axes
B)Calculate coordinate of points of intersection
I have drawn both on axes. I am having trouble with B). I know you have to do y=y.
So far i have done this;
x²3x+2=8x16/x3
(x3)(x²3x+2)=8x16
x³6x²+11x6=8x16
x³6x²+3x=16
x³6x²+3x+16=0
what do i do now?

little mistake:
when you multiply 8x16/x3 by x3
u have to multiply 8x too
