d'oh, my reply didn't send. ):
So, how do you determine whether a polynomial is a factor of another?
I dont know...
you divide and see if it leaves no remainder. no remainder means its a factor!!
Not the answer you are looking for? Search for more explanations.
Well, we can check using division... if their remainder is 0, then the divisor is a factor of the dividend.
Can you show me how to do it using long division please?? thank you...
set y = 2, then the poly = 0.
Solve for k.
I did synthetic division with negative k in the two spots. You will get a remainder as a function of k, set it to zero to find the correct value of k.
yeah, i would have used synthetic division, its easier to keep organized with. :P
but I was wondering how you would do long division in this problem because our professor didn't teach us synthetic division
I think slaaibak's approach is much easier, in that case.
here's how it'd work out in long division (might be hard to read, was all written by mouse)
Yeah, that worked out well. :D
We'd set -5k + 30, our remainder, equal to 0 and solve for k.
That would be the only value that satisfies this problem.
Yeah, I much prefer the other method mentioned or synthetic division, which isn't AS messy, but it just needs space. :)
