Question

subtract this question

Answer 1

$5x {}^{2} y {}^{2} + 7x {}^{2} y - 11xy - (10x {}^{2} y {}^{2} - 6x {}^{2} y - 4xy$

$5x {}^{2} y {}^{2} + 7x {}^{2} y - 11xy - 10x {}^{2} y {}^{2} + 6x {}^{2} y + 4xy$

Adding like terms first

$= 5x {}^{2} y {}^{2} - 10x {}^{2} {y}^{2} + 7x {}^{2} y + 6x {y}^{2} - 11xy + 4xy$

$= - 5x {}^{2} y {}^{2} + 13x {}^{2} y - 7xy$Hence after subtracting we get,

$- 5x {}^{2} y {}^{2} + 13x {}^{2} y - 7xy$
