Find a polynomial function with leading coefficient 1 that has the given zeros, multiplicities, and degree.
zero: 3, multiplicity: 1
zero: 2, multiplicity: 3
degree: 4

zero: 3, multiplicity: 3
zero: 0, multiplicity: 2
degree: 5

We are to find a polynomial function with leading coefficient 1 that has:

4 degrees; 3 zeros; 1 multiplicity

To have 4 degrees the function's variable should have 4 as the highest power. It should also have 3 factors equivalent to 3 zeros. 

Example:

f(x) = x^4 - 2x^3 + 4x^2 - x + 1
