Question 161474
You're doing great. Now you just need to combine like terms. 



The terms that have "xy" and "yx" are the same terms (since you can switch the terms), which that means that {{{3yx}}} is the same as {{{3xy}}}. So the expression also looks like this:



{{{11x^2+44xy+3xy+12y^2}}}



{{{11x^2+47xy+12y^2}}} Now combine like terms.



So {{{(11x+3y)(x+4y) }}} FOILs to {{{11x^2+47xy+12y^2}}}
