Factor, please.
18b^2 - 89b = -36
Thanks. I can't seem to get it.
Can't you do your own math problems?
Natural logs for great justice.
What if you did seem to get it? caterpie;
71/7= b?

lol chinese pplz
Seriously, I'm stuck and it is factorable. PLEASE HELP! I need it done by tomorrow... sweat;
Shit, this is hard. It would be easy if you could pull a number out of 18b2 - 89b +36 = 0, but you can't because 89 is a prime number.
QUADRATIC FORMULA, SIR.

QUADRATIC FORMULA, SIR.
You mean the whole square root of b^2 - 4ac? I tried that, and it works. I tried all factors of 36, and none work! gonk;

Dude, are you sure you've got the problem right? Maybe that's supposed to be a 81, not a 89? Seriously, it wouldn't make sense for them to give you a problem like this if you don't know the whole quadratic formula.

I just checked. It is, in fact, an 89. gonk;
B = 4.5, .444
yey
If I didn't suck total dick at factoring, I'd help you. For now, I think I'll pay attention, since my class is on factoring right now, anyway.

Okay, well thanks anyway. I think I'll just see if anyone in my class got the answer, and if so, I'll just get the factored from them. Maybe it's a typo in the book or something. D:
(9b - 4)(2b - 9)
Holy shit. I didn't even know how to factor, and I got it. I just looked up how to in my book, cause I really wanted to know how...
9b x 2b = 18b2
9b x -9 = -81b
-4 x 2b = -8b
-4 x -9 = 36
All of that shit put together = 18b2 - 89b + 36 = 0
I WIN THE INTERNET
...wow. That's the only combination I didn't try for a 4 and a 9 in the ends of the brackets. IT'S SO FUCKING OBVIOUS TOO.

I know. I can't even factor, and to me it looks just like the shit most of my classmates do with ease.
