Question 321005
{{{(a/(a^2+2a+1))+(2/(a^2+6a+5))}}}
{{{(a/((a+1)(a+1)))+(2/((a+1)(a+5)))}}} multiply by a {{{1/1}}} that creates the same denominator for both fractions
{{{(a/((a+1)(a+1)))((a+5)/(a+5))+(2/((a+1)(a+5)))((a+1)/(a+1))}}}
{{{(((a^2+5a)+(2a+2))/((a+1)(a+1)(a+5)))}}}
{{{highlight((a^2+7a+2)/((a+1)(a+1)(a+5)))}}}
