This is a question I have to do for tomorrow
[tex]\frac{1+4x+4x^2}{x}\times\frac{3x^4}{12x^2-3}[/tex].
I just factor the tops and then cancel where I can. This is what I came up with:
[tex]\frac{3x^4}{12x^3-3x}[/tex]
But the answer key says:
[tex]\frac{x^3(1+2x)}{2x-1}[/tex]
What have I done wrong?
