Question

Subtract (-3y2 − 8) − (-5y2 + 1)

Answer 1

The answer to (-3y² - 8) - (-5y² + 1) is 2y² - 9

Explanation:

`(-3y^2-8)-(-5y^2+1)`

Since there is a minus sign in front of the second parentheses, then the terms within that parentheses will be changed to their opposite signs.

`-3y^2-8+5y^2-1`

Combine like terms.

`2y^2-9`

Answer 2

2 y^2 - 9

Explanation:

(-3y^2 − 8) − (-5y^2 + 1)

Distribute the negative sign

(-3y^2 − 8) + 5y^2 - 1

Combine like terms

-3y^2 + 5y^2 - 1 − 8

2 y^2 - 9
