WakeOfAshes

why dont you make 1 question per post. it's hard to separate the questions.

WakeOfAshes

.......-3x^4 + x^2 - 9x
.....______________________
3x | -9x^5 + 3x^3 -27x^2
...(-)-9x^5
.......-----
...............0 + 3x^3
...................- 3x^3
...................------
............................0 -27x^2
...........................(-)-27x^2


So your answer is -3x^4 + x^2 - 9x. You can check that answer by multiplying "-3x^4 + x^2 - 9x" by 3x. Does it check out? Yes? that is your answer.

Do you get how I did it? all the others should be as simple as that. repeat and recycle. thanks come again.

Adam

i numbered them.

Yo, Jaymoney, how are you at non-space motion in physics?

WakeOfAshes

Ill do one more for you, and answer any other questions you have about the technique but not going to do it all for you. it's too easy

Adam

Thanks once i pick up the steps it will be easy.

WakeOfAshes

yeah.... it's really simple. Ask questions you have about the steps and ill answer away. its really easy stuff. you can get it.

WakeOfAshes

do you get my picture 100%?

6. (m-4)(m^2+2m+3)

Step 1 - Multiply m individually by all "m^2 + 2m + 3"
Step 1 ans = m^3 + 2M^2 + 3m

Step 2 - Multiply -4 individually by all "m^2 + 2m + 3"
step 2 ans = -4m^2 -8m -12

Step 3 - add step 1 + step 2 by combining like terms

Ans = m^3 -2m^2 - 5m -12

Adam

This one is the worst one.

Someone doesn't know how to do synthetic division

WakeOfAshes

For the top :

(X^-4)^2 = (X^-4)*(X^-4) = X^-8 because -4 + -4 = -8

((X^-2) (X^3))^2 = (X)^2 because -2+3 = 1

then x^-8 * X^2 = X^-6 because 2-8=-6

for the bottom

((X^-2) (X^-3))^2 = (X^-5)^2 = (X^-5)*(X^-5) = X^-10

finally

(X^-6)/(X^-10) = X^4 because -6 - (-10) = 4

solved.

Yo, Jaymoney, how are you at non-space motion in physics?

There's a good chance I've seen it before.

Adam

i only need help with a couple more ones.

1. 4xy divided by 12x^4y^3+8x^6y^2-4xy)

2. (y+2)^3

I had the answer for this one but i am not 100 percent it's right

3. (4x^3+2x^2-7x) - (3x^5+5x+7x^2)


last two ones

ZmbieFlavrdCupcakes

wait are you just solving them?
wow, which math are you in?

Adam

Yea I am just solving them. I am in normal college algebra which i am pretty good at besides this shit.

ZmbieFlavrdCupcakes

just combine like terms

ZmbieFlavrdCupcakes

1) 1 over (4x^3y^2+2x^5y-1)
2) y^3+5y^2+12y+8
3) -3x^5+4x^3-5x^2-12x
4) (was the second coefficient in the first polynomial a 4?)
5) 9x^2-30xy-25y^2
