Question 14893
Congratulations on writing the fraction in algebra.com notation!


First step is to factor the numerator and denominator:
{{{ (-3x^2+12)/(x^2-x-2) }}}
{{{ (-3(x^2-4))/(x^2-x-2) }}}
{{{ (-3(x-2)*(x+2))/((x-2)(x+1)) }}}


Next, notice that the factors (x-2) divide out in the numerator and denominator, leaving:

{{{ ((-3)*(x+2))/(x+1) }}}
