Hey Mate!

Here's Your Answer⬇️

★Steps:-

• First, arrange the terms of all the expressions given in the same order.
• The next step is to write these expressions in two rows in a way that the like terms occur one below the other.
• Then change the sign of every term in the lower row from - to + and from + to - .

$4 {x}^{2} - {5y }^{2} + 8xy \\ - 5 {x}^{2} + {2y}^{2} - 3xy \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: ( + ) \: \: \: \: \: \: ( - )\: \: \: \: \: \: \: \: \: ( + )\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ - - - - - - - - - - \\ - 9 {x}^{2} - 7 {y}^{2} + 11xy \\ - - - - - - - - -$
