Question 915730
{{{2(x+y)^2}}}


{{{2(x+y)(x+y)}}}


{{{2((x+y)(x+y))}}}


{{{2(x(x+y)+y(x+y))}}}


{{{2(x^2+xy+yx+y^2)}}}


{{{2(x^2+xy+xy+y^2)}}}


{{{2(x^2+2xy+y^2)}}}


{{{2x^2+4xy+2y^2}}}


-------------------------------------------------------


So {{{2(x+y)^2}}} expands to {{{2x^2+4xy+2y^2}}}
