You can put this solution on YOUR website! This will result in a trinomial and follow these rules to find it.
The first term is obtained by square the first term
6a(6a)=36a^2
The second term is the worst add the two coefficients together, combine the variables and multiply by 2.
6a+11b=17ab==>34ab
The last term is found by squaring the last term.
11b(11b)==>121b^2
