HELP ME!!!

write each polynomial in standard form

1. 4r + 3 - 9r^2 +7r

2. 10x^2+8-6x-10x^2

Simplify each polynomial. Write each in standard form.
HINT: Watch for the operation! Add? Subtract? Or Multiply?
3. (2v^3-v+8)+(-v^3+v-3)

4. (6s^4+7s^2+7)+(8s^4-11s^2+9s)

5. (4h^3+3h+1)-(-5h^3+6h-2)

6. (8z^3-3z^2-7)-(z^3-z^2+9)

7. 5k(3-4k)

8. 4m(2m+9m^2-6)

9. q(11+8q-2q^2 )

10. (x-2)(x+4)

11. (6g+7)(3g-8)

12. (x-1)^2

13. (4y+2)^2

Factor out the GCF (Greatest Common Factor)
Hint: What can you divide every term by?
14. 3b^4-9b^2+6b

15. 4g^2+8g

16. 45c^5-63c^3+27

Factor each polynomial.
HINT: Change from x^2+bx+c to (x+p)(x+q) where p and q are the factors of c that add to b.
17. x^2+8x+12

18. t^2-5t-14

19. p^2-20p+100

20. r^2+6r-40

21. x^2-13x-30

22. d^2-18d+45

It would be amazing if someone could answer these for my portfolio I need to do asap but I just can not figure these out!!!! These are the questions for The Unit 3 Polynomial Sample Work for Algebra 1 Connections Academy
