Question 396150
{{{(4t)/(t^2-1)+(t)/(t-1)}}}
Notice we can factor the denominator of the left term:
{{{(4t)/((t+1)(t-1))+(t)/(t-1)}}}
{{{(4t)/((t+1)(t-1))+t(t+1)/((t+1)(t-1))}}}
{{{(4t)/((t+1)(t-1))+(t^2+t)/((t+1)(t-1))}}}
{{{(4t+t^2+t)/((t+1)(t-1))}}}
{{{(t^2+5t)/((t+1)(t-1))}}}
{{{t(t+5)/((t+1)(t-1))}}}
