Math Help!
Here wee go,

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.



2.) Use synthetic division and the remainder theorem to show that 2 is a zero of y=x^3-4x^2+x+6. Find the remaining zeros.

My Daleks, just understand this; if you choose death and destruction, then death and destruction will choose you.

Well the math I was doing earlier was my main homework on my computer, but what I just posted is from a worksheet wee have to turn in...and usually they have nothing to do with any of the homework or anything wee've done in class, so I'm always lost.

Don't think you can, as that expression looks like a rearrangement of the present value of annuity formula.

C'mon, you should be able to do this one at least. (if not, why are you taking the course again?)

Forgot how to factor things.

I'm taking it again because it's a required class and I failed it the first time around.
I'm an English major so this math spoon is useless to me.

It's just plugging numbers into a formula.  You got to be able to do that - barely harder than year 8 maths.  They'll easily get you on a test if you can't even do that.
