Omg, I can still do math.
Apr. 22nd, 2003 11:20 amI'm ecstatic, I swear. Last night, my friend and I were talking about this one annoying math problem that neither of us could really solve. I wasn't thinking about it too much, though, because my brain isn't made to do math at midnight XD. So I went to bed, and then woke up in the morning and was thinking of my friend. Then I thought of the problem XD. It suddenly came to me , though, like *BLING*. I was in a frenzy and had to check it out, so I jumped out of bed and started solving it.
"The sum of two consecutive even integers is 244" . It's easy to just do number crunching and find out that the answers are 10 and 12. I told my friend that last night XD. But that wasn't good enough, you have to write an equation. It's so simple 0__o, I should have put more thought into it last night.
The equation is
X^2+(x+2)^2=244
I did the quadratic formula... but you can just factor the rest of it and wind up with the trinomial
2x^2+4x+4=244
2x^2+4x-240=0
and then factor and shit ---->
2(x+12)(x-10)= 0
SO THE ANSWERS ARE -12 and 10.
THE END VOILA BOOYAKA.
I'm so smart, omggg.
haha, right XD. Now if only my friend were taking trig... ^_^**.
