Find the difference of (−y2+y+2)−(y2−5y−2)

The difference is

2y

Step-by-step explanation:

(-2y+y+2)-(2y-5y-2)

=(-y+2)-(-3y-2)

Remember, then we open parenthesis. When we have -(-3y), we multiply - times -, which is always +.

=-y+2 [+] 3y-2

Then, we add the y terms and the numbers.

=2y+2-2

=2y+0

=2y.

Also, just to clarify, if this is simplifying, then the answer is 2y, but if this is an equation, pls rewrite your question. I hope this helped you :3

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
