Question

Subtract 2xy - a² - b²from x² - 2xy + y², and
from the remainder (i.e., the difference) obtained,
subtract x² + y² + a² +b²​

Answer 1

Answer:

2x^2 - 4xy

Step-by-step explanation:

plz write like terms under like terms

also note that while subtracting sign changes....

x^2 - 2xy + y^2 + 00 + 00

- 00 + 2xy + 00 - a^2 - b^2

(+) (-). (-). (+). (+)

__________________________

x^2 - 4xy + y^2 + a^2 + b^2

___________________________

x^2 - 4xy + y^2 + a^2 + b^2

- x^2 + 0 + y^2 + a^2 + b^2

(+). (-). (- ). (-) (-)

____________________________

2x^2 - 4xy + 0 + 0 + 0
