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++6h-2)

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 these are the questions for the unit 3 polynomial sample work for algebra 1 connections academy

4x3 – 4x2 + 12x2 – 7x – 12x – 21. 4x3 + 8x2 – 19x – 21. That was painful! Now I'll do it vertically: 4x^2 – 4x – 7 is positioned above x + 3; first row. That was a lot easier! But, by either method, the answer is the same ...

Step-by-step explanation:

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
