## anonymous 3 years ago What is the simplified form of x minus 4 over x squared minus x minus 12 • x minus 4 over x squared minus 8x plus 16 ?

1. anonymous

$\frac{x-4 }{ x^2}-12*x- \frac{ 4 }{ x^2 }-8x+16$

There is it set up, now, what can you do first to simplify?

3. anonymous

Also congrats on your first question in mathematics.

4. anonymous

Thanks!

so, first, I should multiply12 and x, so I get 12x, and then I combine like terms, right? so, simplified it would be $(x-8)-20x+16$right?

6. anonymous

You cannot combine 12 and x.

7. anonymous

I can't? I thought it that when you multiply a number and an unknown, you get $number(unknown)$

$\frac{ x-8 }{ x^2 }+2x+16$
