what is the product in simplest form x^2+5x+6/x+4 * x^2+x-12/x^2+x-2 state any restrictions on the variable
Please help me, and thank you. I will be sure to like you on google chrome
<pre>With {{{system(x <> - 4, x <> 2_and, x <> - 1)}}}, {{{((x^2 + 5x + 6)/(x + 4)) * ((x^2 + x - 12)/(x^2 + x - 2))}}} ------> {{{((x^2 + 5x + 6)/(x + 4)) * ((x^2 + x - 12)/((x - 2)(x + 1)))}}} reduces to: {{{highlight(highlight_green(highlight((x^2 - 9)/(x - 1))))}}}
