Question

Find the value of: Adding (-x2- y2- 1) + (y2- 1b- x2) + (1 -x2- -y)​

Answer 1

Answer:

-6x +y +1b

Step-by-step explanation:

means = (-2x-2y-1) + (2y-1b-2x) + (1-2x-(-y))

(-2x-2y-1) + (2y-1b-2x) + (1-2x+y)

-2x - 2y - 1 + 2y - 1b - 2x + 1 -2x + y

Now group like terms.

(-2x - 2x - 2x) (- 2y + 2y + y) (-1 + 1) (1b)

-6x + y + 0 + 1b

-6x +y +1b
