$\left(\begin{matrix}x \\ x^2+4x-12\end{matrix}\right)+\left(\begin{matrix}6 \\ x^2+4x-12\end{matrix}\right)$

is it $\frac{x}{x^2+4x-12}$

3. alexsu22

no it should be something like x/x-5 that isnt the answer that is an example

5. alexsu22

Oh yes it is like that.

$= \frac{x+6}{x^2+4x-12}$ factorise x^2 + 4x-12 =$\frac{x+6}{(x-2)(x+6)}$ $= \frac{1}{x-2}$

Thanks
