[tepsu]

It's been hell of a good day ! Today I found out that I'm getting a new computer for sure this weekend cant wait for that, also got my avg. rank to 978 at least for a while, broke 12 000 games played, ffr overall rank <500 AND I FC'd my first FMO yayyyy \o/
Im so happy that im going to give 10k credits to the first 1 who solves my math homework

Only 2 calculations just solve these, and I want also the calculation not just the answer cus I got them in my book n_n

x^3 + x^3 - 30x = 0

and 2x^3 + 36x^2 = -162x

I know easy math, but I'm just in highschool and I really suck at these

x^3 + x^3 - 30x = 0 ---> 2x^3 - 30x = 0 ------> 2x(x^2 - 15) = 0 ------> (solve inside)
X^2 = 15 ------>
x = +/- Sqrt(15) and 0



2x^3 + 36x^2 = -162x --> 2x^3 + 36x^2 + 162x = 0 --> 2x(x^2 + 18x +81) = 0 ----> 2x(x+9)^2 ----->
x = 0, -9(double root)

/bored, chunky, If your still working on this speed it up man!

I dno, In finland they just call it short and long math, short is the basic one so im in there and longer is more advanced wich is more respected for example when applying for a job but I just dont have math in me, I understand all the forms and **** but I just cant twist em :P
