Hi
*Note: will express both terms with common denomiator %2818y%5E2%29%29
%28%288%29%2F%289y%29%29-%28%285%29%2F%2818y%5E2%29%29
.
Multiply both numerator and denominator of first term by 2*y
%2816y%2F18y%5E2%29-%28%285%29%2F%2818y%5E2%29%29
.
Express with the common denominator
%2816y-5%29%2F%2818y%5E2%29%29
