Question

12(3y-1)-3(4y+2) -7y(y^2+2y-8)

Answer 1

$36y - 12 - 12y - 6 = 24y - 18 = 6(4y - 3) \\ - 7 {y}^{3} - 14 {y}^{2} + 56y$

Answer 2

To simplify the given expression, follow these steps:

1. Distribute the coefficients outside the parentheses to the terms inside the parentheses.
2. Perform any necessary operations within the parentheses.
3. Combine like terms, if possible.

Let's go through it step by step:

Step 1: 12(3y - 1) - 3(4y + 2) - 7y(y^2 + 2y - 8)

Apply the distributive property: = 12 * 3y - 12 * 1 - 3 * 4y - 3 * 2 - 7y(y^2 + 2y - 8)

Step 2: Perform operations within parentheses: = 36y - 12 - 12y - 6 - 7y(y^2 + 2y - 8)

Step 3: Combine like terms: = (36y - 12y - 7y) - 12 - 6 - 7y(y^2 + 2y - 8)

= 17y - 18 - 7y(y^2 + 2y - 8)

Now, the expression is simplified and cannot be further simplified without more information or additional instructions.
