Question

Find the sum of expressions-
2x2-8xy+7y2-8xy2, 2xy2+6xy-y2+3x2, 4y2-xy-x2+xy2

Answer 1

Please mark me brainalist

The sum of the given expressions =(2x2 + 3x2 – x2) + (-8xy + 6xy – xy) + (7y2 – y2 + 4y2) + (-8xy2 + 2xy2 + xy2)

= 4x2 – 3xy + 10 y2 – 5xy

Answer 2

Step-by-step explanation:

(2x^2 - 8xy + 7y^2 - 8xy^2) + (2xy^2 + 6xy - y^2 + 3x^2) + (4y^2 - xy - x^2 + xy^2)

(2x^2 + 3x^2 - x^2) + (-8xy + 6xy -xy)  + (7y^2 - y^2 + 4y^2) + (-8xy^2 + 2xy^2 + xy^2)

4x^2 - 3xy + 10y^2 - 5xy^2
