Question

i) 2x(x - y) - 3y(xy + 2x) - xy(x + y)​

Answer 1

Answer:

$2x(x - y) - 3y(xy + 2x) - xy(x + y) \\ 2x \times x - 2x \times y - 3y \times xy + 3y \times 2x - xy \times x + xy \times y \\ {2x}^{2} - 2xy - {3xy}^{2} + 5xy - {x}^{2} y + {xy}^{2} \\ {2x}^{2} - 2xy + 5xy - {3xy}^{2} + {xy}^{2} - {x}^{2} y \\ {2x}^{2} + 3xy - {2xy}^{2} - {x}^{2} y$
