## clamin one year ago PLEASE HELP!!! MEDAL!!! Use synthetic division to solve.

1. Nnesha

yayyay!

2. clamin

$\left( -15p^4+\frac{ 21 }{ 2} p^3-\frac{ 45 }{ 2 }p^2+63p-36\right) \left( 9p-9 \right)$

3. clamin

there a division sign in between the parenthesis i forgot to put it

4. Nnesha

;-; ugly q

5. Nnesha

alright first set 9p-9 equal to zero then solve for p 9p-9 = 0 p =?

6. clamin

p=1

7. Nnesha

right now right the coefficients|dw:1443658432075:dw| carry down the leading coefficient then multiply by 1 write the answer above the line and then combine them

8. clamin

|dw:1443658410770:dw| thats all i got so far

9. clamin

i know the steps i just hate solving the fractions @Nnesha

10. Nnesha

aw same here i don't like fractions :/

11. Nnesha

so it's $\frac{ 21 }{ 2}-15$ -15 is same as -15/1 $\frac{ 21 }{ 2}-\frac{15}{1}$find the common denominator

12. clamin

3

13. Nnesha

wait do you mean 3 is a common denominator ?

14. Nnesha

when the denominator are not the same we should multiply them

15. Nnesha

hey understand ? let me know if you have any quesitno :=)

16. Nnesha

question *

17. clamin

21 and 15 common denommintor is 3 right??

18. Nnesha

no common denominator is 2 like i said when the common denominator aren't the same we should multiply them 2 times 1 = 2 $\frac{\color{ReD}{ 1}(21)-\color{blue}{2}(15) }{ 2}$ and when we write it as common denominator we should multiply the numerator of first fraction with the denominator of 2nd fraction and multiply the numerator of 2nd fraction by the denominator of 1sst one

19. Nnesha

now simplify it

20. clamin

9/2

21. Nnesha

ye but its supposed to be negative

22. Nnesha

anywz -2 times 15=-30 (21-30)/2 = -9/2

23. Nnesha

|dw:1443660319587:dw| now repeat the step

24. Nnesha

|dw:1443660350489:dw|$-\frac{ 45 }{ 2 }-\frac{ 9 }{ 2}$this one would be easy denominators are the same

25. clamin

18

26. Nnesha

hmm no how did you get that ?

27. clamin

$-15p^4-\frac{ 9 }{ 2 }p^3+18p^2+81p+45$ this is my final answer @Nnesha

28. Nnesha

18 isn't correct

29. clamin

i subtract 45-9=36 so its 36/2 =18

30. Nnesha

it's -45

31. clamin

ohh yea i forgot that it negative

32. clamin

i got 27

33. Nnesha

-45-9= ??

34. Nnesha

when u add two negative number answer would be what ??

35. Nnesha

u there ?? @clamin

36. clamin

positive

37. clamin

-54

38. Nnesha

right -54 so divide 2 =-27 negative not positive
