Answer:
If the equation was intended to be written as:
(y² + 4y +7) – (4y² + 3y – 2)
Then the answer is:
-3y² + y + 9
Step-by-step explanation:
Original equation:
(y² + 4y +7) – (4y² + 3y – 2)
The minus sign must be distributed through the terms within the parenthesis. Thus – (4y² + 3y – 2) becomes – 4y² – 3y + 2 and the parenthesis is no longer needed.
Remove bother parenthesis after distributing the negative sign:
y² + 4y + 7 – 4y² - 3y + 2
Gather like terms, that is put terms together than can be combined:
y² – 4y² + 4y - 3y + 7 + 2
Simplify by combining like terms:
-3y² + y + 9
