Question 206535
{{{2(8x^2y-7xy+3xy^2)-(3x^2y-9xy^2)}}} Start with the given expression.



{{{2(8x^2y)-2(7xy)+2(3xy^2)-3x^2y+9xy^2}}} Distribute



{{{16x^2y-14xy+6xy^2-3x^2y+9xy^2}}} Multiply



{{{13x^2y-14xy+15xy^2}}} Combine like terms.



So {{{2(8x^2y-7xy+3xy^2)-(3x^2y-9xy^2)}}} simplifies to {{{13x^2y-14xy+15xy^2}}}



In other words, {{{2(8x^2y-7xy+3xy^2)-(3x^2y-9xy^2)=13x^2y-14xy+15xy^2}}}
