Question

(xy² + 4x²y-7x²y- 3xy²)+(x²y+xy²) ​

Answer 1

Answer:

$(-2x^2y) + (-xy^2)$

Explanation:

${(xy^{2}+4x^{2}y-7x^{2}y-3xy^{2})}\atop{+(x^2y + xy^2)}$$= {(4x^2y-7x^2y)+(xy^2-3xy^2)}\atop{x^2y+xy^2}$$= {(-3x^2y) + (-2xy^2)}\atop{+x^2y + xy^2}$ $= ((-3x^2y) + x^2y)+((-2xy^2) + xy^2) = (-2x^2y) + (-xy^2)$
