Question

the polynom
7x + 8
1. (3x + 2) + (4x + 6) -
2. (12y + 17y - 4) * (9y+ - 13y + 3) = 21y2 + 4y - 1
3. (6x - 4x + x - 9) - (3x² + 7x + 3) =
4. (3x - 4x - 1) + (x - X+6)=

Answer 1

Answer:

Do you want the answer for all of them

Step-by-step explanation:

Answer 2

3. The negative in the middle distributes whatever’s in the parentheses to the right.

6x^3-4x^2+x-9-3x^2-7x-3=

Then you combine like terms

6x^3-4x^2-3x^2+x-7x-9-3

[6x^3-7x^2-6x-12]
