Find the polynomial function with roots 1, 7, and –3 of multiplicity 2 help please:)
-3 has multiplicity two means \[(x+3)^2\] is a factor
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"
multiply all of those together so it would be 3x +1?
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
