So, i've got a group project. My partner is a wuss and wants to go to bed (It's 12:57am here), but i want to turn this in tomorrow and get the extra credit. Apparently my working all day isn't as rough as his day of gaming.
Anyhow, that's beside the point.
We're being asked to describe in detail how we got our answer, and show the steps involved.
This isn't really tough, but i will be honest, my brains a little fried after the past 10 hours in the kitchen at work.
Anyhow, if you want to give it a go, i will be doing it myself, and i would definitely love if someone who did it correctly would post their thoughts and answers and i can compare and see what's right, or where i went wrong.
Here's the problem:
"Only one positive integer, when squared is 4 times the sum of 24 and the integer.
Determine the integer"
Anyhow, if anyone wants to help, i will greatly appreciate it. Like i said, i'm not trying to get anyone to do my work for me, but i wouldn't mind some outside help.
Thanks in advance facepunch.
I already have problems with Algebra on my own, I'm not solving yours too.
since i'm feeling nice, the answer is 12.
12^2=144
24+12=36
36*4=144
just use trail and improvement.
it took me literally 8 seconds in excel to come up with that

This, well I don't know how to solve stuff in excel, but I could solve that on paper in a matter of seconds...
To solve it algebraically, X^2=4(24+X) X^2=96+4X X^2-4X-96=0 then solve quadratic as normal, getting positive 12 and negative 8. The question instructs you to take the positive integer, so use 12.
