No... I am not recruiting for the answers to one...
I am testing your math skills... sort of

OK... 5 Questions (some with Sub-questions), no calculator, and 5 minutes. Can you make it?
I'm just kidding, take the time you want... and you would probably need an graphical calculator for some questions so...
Assignment 1
z^2 - 12z + ?
  1. What number shall be instead of the questionmark so that the expression would be possible to write as an binomial squared?
  2. What will the binomial be?

Assignment 2
  1. Multiply (y + 7)^2
  2. Use the answer to solve the equation y^2 + 14y + 49 = 9.

Assignment 3
Solve the equation; 21x^2 – 4x – 1 = 0. USE EXACT ANSWERS

Assignment 4
Draw the graph to the linear function H, where H(x) > 0 when x > 3 and H(x) < 0 when x < 3

Assignment 5
H(n) = -32200 – 608n + 2n^2

Count the root for the function H(n).

^2 means squared, for those that did not understand...

Send any answers by PM... or use the "spoiler" function...
I will post how many correct answers you have...

Solemn 3/5 (so far)
My personal collection of creatures

Leenalia (sorry that you accidentally became a male )

Other creatures

Currently halting all attempts at raising more dragons due to full quota of dead hatchlings
(Already have more than 10 dead'uns, don't want more)

Focusing on keeping my sanity.
Insanity progress paused at four "me"

I'll edit these in as I figure them out. This is pretty much basic algebra, but your assignments are worded weirdly, so I'll figure them out a bit at a time.

Assignment One:

a. ? = 36 = [1/2 x (-12)]^2
b. z - 6

Assignment Two:

a. (y + 7)^2 = y^2 + 14y + 49
b. (y + 7)^2 = 9; y +7 = 3; y = -4

Assignment Three:

21x^2 – 4x – 1 = (7x + 1)(3x - 1) = 0; 7x + 1 = 0 or 3x - 1 =0; x= -1/7 or x = 1/3; both are correct when substituted, so neither one is extraneous.

Assignments Four and Five...I'm too lazy to graph and do... D: Maybe when I have time...

Lol, just highlight if you want to see it better...also too lazy to make it a spoiler. OPEN TO THE PUBLIC!
