Question 158074
Simplify:
{{{(18x/(x^2-5x-36))+(2x/(x+4))}}} Did I get this right? If so, then factor the denominator of the first fraction.
{{{(18x/(x+4)(x-9))+(2x/(x+4))}}} The common denominator is {{{((x+4))((x-9))}}} so multiply the second fraction by:{{{(x-9)/(x-9)}}} to get:
{{{(18x/(x+4)(x-9))+(2x(x-9)/(x+4)(x-9))}}} Perform the indicated addition.
{{{(18x+2x(x-9))/(x+4)(x-9)}}} Simplify.
{{{highlight(2x^2/(x^2-5x-36))}}}
