2)y=8x-16/x-3

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;

x²-3x+2=8x-16/x-3

(x-3)(x²-3x+2)=8x-16

x³-6x²+11x-6=8x-16

x³-6x²+3x=-16

x³-6x²+3x+16=0

what do i do now?

when you multiply 8x-16/x-3 by x-3

u have to multiply 8x too
