Question 346242
Use the common denominator, {{{(x-5)^2}}}
{{{7/(x-5) + 28/(x-5)^2=(7(x-5))/(x-5)^2 + 28/(x-5)^2}}}
{{{7/(x-5) + 28/(x-5)^2=(7(x-5) + 28)/(x-5)^2}}}
{{{7/(x-5) + 28/(x-5)^2=(7x-35+ 28)/(x-5)^2}}}
{{{7/(x-5) + 28/(x-5)^2=(7x-7)/(x-5)^2}}}
{{{7/(x-5) + 28/(x-5)^2=highlight((7(x-1))/(x-5)^2)}}}
