Someone please find it in your hearts to do this! Please!!!
Devide using polynomial long divison.
P.S I do NOT know algebra! So I wouldn't know how to do this at all.
Please take your time on this..
May it please be completed by tomorrow? Thanks
(3x^2 + 11x + 1) / ( x - 3)
(x^3 - 3x^3 + x - 8) / (x - 1)
(10x + 27^2 + 14x + 5) / (x^2 + 2x)
Devode using syntheic division
(x^3 - 14x + 8) / (x + 4)
(3x^2 - 10x) / (x - 6)
(x^4 - 6x^3 - 40x + 33) / ( x - 7)
Factor the polynomial given that f(k) = 0
f(x) = x^3 - 3x^2 - 16 - 12; k = 6
f(x) = x^3 - 11x^2 + 14x + 80; k = 8
Given one zero of the polynomial function, find the other zeros.
f(x) = x^3 + 11x^2 - 150x - 1512; - 14
f(x) = 4x^3 + 9x^2 - 52x + 15; - 5
Thank you very much for taking the time to help me!
Please complete by tommorow PLEASE!!! I will be your biggest fan!!! please someone help =(
PLEASE HELP!!! I GOT TILL Wednesday!!! or I'm dead
Someone please!!!
John,
I sent you a PM as well. I'm sorry I could not build this in time for your exam, but I think it's still useful for you and others to put this on here now. For your other "non-cubic" equations, I'm working on a lesson over the next few days. For now, I just built something for you that can answer the cubic questions you asked in the form .
Go here:
Soving Cubic Equations
Enter your coefficients and press the 2nd button that says "Guess 1 Root-Synthetic Division/Quadratic Method"
For the 4 problems you entered, it shows you the synthetic division. However, my calculator uses a root ranking system, so the other 3 problems you asked about for cubics, my calculator finds that root, but uses a different root to divide. Try the equation above I quoted you on, that will show you how to work this. For your other 3 cubic equations, feel free to use the calculator, but first, try to match what it does before you use it. It uses a different root to divide for the synthetic division then your question asks, but I think that is a good check for you to try to see if you can do the synthetic division to get to the root your question asks you for!
Scroll down a bit and you will see the synthetic division. It starts at the sentence that says "Now Let's perform synthetic division using Ruffini's Rule to check for other roots:" After synthetic division completes, the calculator uses the quadratic rule to solve for the remaining 2 roots.
Also, a nice writeup about Ruffini's rule which my calculator uses is seen here ---> Ruffini's rule - Wikipedia, the free encyclopedia
Let me know if you have questions.
