Question

4y-(y-4)-(y-8)² Помогите

Answer 1

4y -(y -4) -(y-8)² = 4y -y + 4 - (y² - 16y + 64) = 4y - y + 4 - y² +16y - 64 =
-y²+19y - 60

Answer 2

Simplifying the Expression

To simplify the expression 4y-(y-4)-(y-8)², we can follow the order of operations (PEMDAS/BODMAS) and simplify each part step by step.

1. Simplify the expression inside the parentheses: (y-4) and (y-8)².

- (y-4) remains the same. - (y-8)² can be expanded as (y-8)(y-8), which simplifies to y² - 16y + 64.

2. Substitute the simplified expressions back into the original expression:

4y - (y-4) - (y-8)² becomes 4y - (y-4) - (y² - 16y + 64).

3. Simplify further by distributing the negative sign to the terms inside the parentheses:

4y - (y-4) - (y² - 16y + 64) becomes 4y - y + 4 - y² + 16y - 64.

4. Combine like terms:

4y - y + 4 - y² + 16y - 64 simplifies to 19y - y² - 60.

Therefore, the simplified expression is 19y - y² - 60.
