Find the polynomial function with roots 1, 7, and –3 of multiplicity 2 help please:)

OpenStudy (anonymous):

-3 has multiplicity two means \[(x+3)^2\] is a factor

OpenStudy (anonymous):

so write \[(x-1)(x-7)(x+3)^2\] and then if you have to multiply out, or cheat

http://www.wolframalpha.com/input/?i=%28x-1%29%28x-7%29%28x%2B3%29^2 answer you want says "expanded form"

OpenStudy (anonymous):

multiply all of those together so it would be 3x +1?

OpenStudy (phi):

It is going to be a 4th degree polynomial (i.e. messy!) Here is how to start http://www.khanacademy.org/video/multiplying-polynomials1?playlist=Algebra+I+Worked+Examples
