Question

6x2y2-7x2y+4xy2+11 from5x2y2-3x2y+5xy2+7​

Answer 1

Answer:

$(5x^2y^2 - 3x^2y + 5xy^2 + 7)$ $- (6x^2y^2 - 7x^2y + 4xy^2 + 11)$ $= -x^2y^2 + 4x^2y + xy^2 - 4$

Step-by-step explanation:

$(5x^2y^2 - 3x^2y + 5xy^2 + 7)$ $- (6x^2y^2 - 7x^2y + 4xy^2 + 11)$

$= (5x^2y^2 - 6x^2y^2) - (3x^2y - 7x^2y) + (5xy^2 - 4xy^2) + (7 - 11)$  [rearranging like terms]

$= -x^2y^2 + 4x^2y + xy^2 - 4$
