1)y=x²-3x+2
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?

  • math - ,

    little mistake:
    when you multiply 8x-16/x-3 by x-3
    u have to multiply 8x too
