Here's what I've done so far:
(u-3)^3-3u+8=0
(u-3)(u2-3u+9)-3u+8=0
u3-3u2+9u+92-3u2=27=3u+8=o
u3-9u2+18u-19=0...

but I don't know how to continue on now...

Thanks all in advance =D

The question is:

x^4-21x^2-100=0;-2i

Does anyone understand this? Because I certainly don't...

Thanks for your help!

Hey guys,
I am in Math 12 and I need some help with my review on transformations. Please help if you can.

If the graph x^2 + y^2 = 4 is vertically compressed by a factor of 1/5, then reflected in the y-axis, determine an equation for the graph.

Definition of a continuous function:

a) f(c) is defined

b) lim f(x), x-> c exists

c) lim f(x)= f(c) x->c

If conditions b and c hold true, is a automatically true?

Problem 1:

(x) over (x + 5) - (3X) over (x +2) is equal to (4) over (x^2 + 7x + 10)

** I know that I need to use the quadratic formula at the end there -- that's where I'm getting stuck.

Problem two:

(4) over (x - 1) is equal to (X) over (x + 2) - (6) over (x^2 + x - 2)

how do you make a table of values for this absolute valued function? I don't get it. please help

f(x) = |x-3|

My friend is stuck on a math question. You have to factor two numbers and turn it into 4 numbers (I got stuck cause it made no sense to me). So like, you have to factor a polynomial and make it into 4 numbers into one (no brackets... would it be called a quadromial? I don't think it would be...)
So you have 3x2 - 75
3x2=3 squared

We think it has to do with the greatest common factor (which would be 3).

Any idea? (if you get it and can get an answer, can you show the work?)

I know there isn't much info but that's all I can explain cause it's on a sheet with a pile of other answers and the answers each have a word and when you put it into a spot on the sheet it'll make a (logical) sentence...

I was wondering is it possible to say that sqrt ( sine squared x) is sine. Or can say (sin^2(x))^1/2=sin(x )is that possible?

A group of people attended a play. The group was able to buy a maximum of ten tickets in advance at a reduced price of 8$ per ticket. The rest of the tickets were purchased at the theater at the regular price of 12$ per ticket. The group decided to divide the total cost evenly among all 16 people. How much did each person pay.

If you are gonna answer in a rude way then don't bother answering at all because I will report you.
