Question

Add 2x2–5x2y2+2xy and 6xy+4x2-7 and subtract the result from –xy+x2+7x2y2.

Answer 1

5x2-12x2y2+9xy-7

Step-by-step explanation:

try to rearrange the equation in a convinent way to add Or subtract easily.

now,

2x^2 - 5x^2y^2 + 2xy + 0

(+) 4x^2 + 0x^2y^2 + 6xy - 7

______________

6x^2 - 5x^2y^2 + 8xy - 7

______________

from the obtained solution,

6x^2 - 5x^2y^2 + 8xy - 7

(-) x^2 + 7x^2y^2 - xy + 0

______________

5x^2 - 12x^2y^2 + 9xy -7

______________
