the equation:

P(x)= -4x (x-2)^2 (x+2)^3

what does it mean when they ask to "describe the behavior of the function at each x-intercept that corresponds to a repeated factor???

Simplify. I got 2xy but I do not think I did this right any help? I tried to reverse the second one and multiply but I think I got way off track.

find all the solutions/values of the ff. probs: (value/s of x)

1) x + x^(1/2) = 20
2) cube root of x^2 - 1 = x - 1
3) x^-4 - 13x^-2 + 36 = 0
4) (square root of 8x + 7) - x = 0
5) (square root of 11-x) - (square root of x+6) = 3
6) 3(x+3) + (square root of x+3) = 2

Thanks

find a third degree polynomial with real coefficients and with zeros 1 and -4+i
the answer given is z^3+7z^2+9z-17

I need the formula to work this problem and then I think I am mostly getting hung up on how to multiply the last part of the problem...I used this formula that someone gave me z-z1*z-z2*z-z3

here is what I did:
(z-1) (z-(-4+i)) (z-(-4-i))
(z-1) (z+4-i) (z+4+i)
(z-1) (z+4)^2 +1
(z-1) (z^2+8z+16+1)
(z-1) (z^2+8z+17)
is this right so far?? if it is then this is where I start having problems, if not then what am I doing wrong??

I have been trying to figure it out all day and I just can't. I have emailed a math tutor, I'm still waiting on his response. My professor is going to be conducting an online chat tonight at 10:30 and I plan on being there for that, so don't tell me to do my own homework because I'm trying, I just don't get it! Here's the problem:
I am creating a chart to show a company's revenue. The formula is
Total Costs=Variable Costs + Fixed Costs
C(x)=mx+y
where x represents the number of items produced, m represents the cost to produce each item, and y represents the fixed costs.
These are the graphs I have to create:
Quadratic
Polynomial
Rational
Exponential and
Logarithm.
I could figure out the graphs using Excel but I need the equations. Please don't try to explain it to me using a bunch of math lingo and mumbo jumbo because I don't understand it at all. Just give me the equations.

x-->0 (cos(mx) - cos(nx)) /x^2
because 0/0: L'Hosp.

x-->0 -m*sin(mx)m + n*sin(nx) /2x
because 0/0: L'Hosp.

x-->0 [(n^2)(cos(nx))+sin(nx)-(m^2)cos(mx)-sin(mx)]/2
reduce:
x-->0 [(n^2) -(m^2)(-1)]/2

[(n^2) + (m^2)]/2 <---***Wrong!***
