1.) If P is the principal, or amount borrowed, i, is the monthly interest rate (as a decimal), and n is the number of monthly payments, then the amount, A, of each monthly payment is:

                 Pi
   A=  ___________             (Read as: A equals Pi over 1 minus 1 over (1+i) raised to the nth)
             1 - 1
                 _______
                 (1+i)^n

a.) Simplify the complex rational expression for the amount of each payment.

b.) You purchased a $30,000 car at 1% monthly interest to be paid over 48 months. How much do you pay each month? round to the nearest dollar.

Are you sure you copied that right?

I have never seen an anuity formula which requires Pi.  I have never seen any formula in finance that requires Pi.  Pi is related to geometry (angles, circles, that kind of shit).  Finance is fucking money.  FUCK, write P*i instead of Pi.

Then it should be trivial, no tricks or anything at all.  Just stick the numbers into the formula, get answer.

I can see why Zinga refused to help you.  And I will do so for the same reason.

They already gave you the formula.  Which you can apply without any further mathematical manipulation.  What more do you want?

Don't know what the fuck you need to do with the remainder theorem.  I don't even remember what the remainder theorm is any more...

But to solve that, since they already told you 2 is a root... just divide that whole thing by (x-2), then you end up with an order 2 polynomial (quadratic) which you can factorize via standard methods.
