So therefore, when you're taking the square root of a variable, it can be positive or negative?

But if it's a constant, it's only positive, right?

Do you mean 0.519 dollars per share? If so:

4,000 * .519 = $2076
20,618 * .485 = $9999.73
11,904 * .425 = $5059.2

Add them all up and you get:
$2076 + $9999.73 + $5059.2 = $17,134.93
This is the cost of all the shares.

Now we take that number and divide it by the number of shares we have (32,522).

$17134.93/32522 = $0.526871963

Therefore, the average share price is 52.7 cents a share.

Yup, I had a good look at it.

Took me a while to understand it all but I see the logic behind it.

Thanks for the taking the time to explain all the steps guys. I appreciate it.

Awesome, thanks a lot for the help. I don't know why you decided to divide a standard linear polynomial though. I would've NEVER thought of that.

Glad I stumbled across these forums, just for general purpose as math is awesome.

Alright so let me try to decipher this and you can tell me if I did this correctly or not.

y = mx+b is the standard form for a linear equation

So we divide the polynomial by a linear equation in the form (x-b) where b is equal to 1
(mx +b) / (x-1) = m with remainder m + b

(mx+b) / (x+2) = m with remainder -2m + b

We solve for the variable b in each case.
m + b = 2
b = 2-m

-2m + b = -19
b = 2m - 19

Let b = b and solve for m
2-m = 2m-19
3m = 21
m = 7

Substitute m = 7 into b = 2-m
b=2-m
b=2-7
b=-5

But these into the form P(x) = mx +b
P(x) = mx +b
P(x) = 7x -5

How's that?

If you want to solve for m and x (respectively), you'll have to tell us what the other side is equal to.

Also, is it 9/(m+7) or (9/m)+7?
