Question

1. -{6x²-3xy+[7x²-8xy-(2-2y)-10y²]}+11y²
the answer is x²+y²-5xy-2y-2 I need solution.

Answer 1

open ()
\[-\left\{ 6x^{2}-3xy+\left[ 7x^{2}-8xy-2-2y-10y^{2} \right] \right\}+11y^{2}\]
open []
\[-\left\{ 6x^2-3xy+7x^2-8xy-2-2y-10y^2 \right\}+11y^2\]
open{}
\[-6x^2+3xy+7x^2-8xy-2-2y-10y^2+11y^2\]
group like terms
\[-6x^2+7x^2-10y^2+11y^2+3xy-8xy-2y-2\]
solve them
\[x^2+y^2-5xy-2y-2\]
