Question

Subtract and simplify.

(y² - 3y - 5) - (-y² − 7y + 4)

A. -2y^2 - 10y - 1
B. -2y^2 - 7y + 1
C. 2y^2 + 4y - 9
D. 2y^2 - 10y + 4

Answer 1

Explanation:

To subtract and simplify (y² - 3y - 5) - (-y² − 7y + 4), we need to distribute the negative sign to the second set of parentheses:

(y² - 3y - 5) + (y² + 7y - 4)

Now we can combine like terms:

2y² + 4y - 9

Therefore, (y² - 3y - 5) - (-y² − 7y + 4) simplifies to 2y² + 4y - 9.
