Question

a. xy square + 4y from 5y - 2xy square ​

Answer 1

Answer:

Given :

$subtract \: ( {xy}^{2} + 4y) \: from \: (5y - {2xy}^{2})$

Solution :

$(5y - {2xy}^{2}) - ( {xy}^{2} + 4y)$

$5y - {2xy}^{2} - {xy}^{2} - 4y$

$- {2xy}^{2} - {xy}^{2} + 5y - 4y$

$- {3xy}^{2} + y$

$y - {3xy}^{2}$

$ans. \: \: y - {3xy}^{2}$

Hope it helps.
