yeah stay away from derivatives, that'll just make him more confused

dark, that's getting into derivatives and calculus.

aha! but ecstasy he's new, plus he posted something that was (then) important to the topic. unlike calum who abused this.
just make sure to look at the dates in posts :) (in top right of a post) and make a guess on if this topic is dead or not :)

first post whats up!?!? http://www.tsugaming.com/forums/viewforum.php?f=344

But thank you for trying to help! You should introduce yourself in the correct forum. =D

10x^3+10x^2+3x+3

isnt it
30x^2+20x+3=0

so that means

30x^2+20x=-3
x(30x+20)=-3

so x=0 or x= 1,5?

if it's not initially set equal to something, you can't make an equation out of an expression

now this new problem is factorable... use basic FOIL factoring if you can see it, or synthetic divison, either will work

the result should be (x+1)(10x^2+3)

if you need an explanation of how synthetic division works, let me know and i'll draw it up on my tablet and post in this thread

nice, well... here's the same type of problem with different numbers, still dont get anywhere. I'll check with my teachers tomorrow, i will "fight" the man, even though my math teacher is a WOMAN :P :)

EDIT::::: Im an idiot i forgot to put in numbers =D

10x^3+10x^2+3x+3.... gotta factor it.... sooooo
x(10x^2+10x+3)=-3
i dunno, could this just be answer? like farn's as well, that all you can do to it? anyway i'll get back to it tomorrow

Re: Algebra 2 stuff

no this is just general polynomial factoring and even if it was set equal to something, you'd still have to maneuver it such that there was a zero on the right in order to get any answers

2x^3-7x^2-19x+35

x(2x^2 - 7x - 19) = -35

wtf o-o

is it set equal to something?

Re: Algebra 2 stuff

by raulperez » October 22nd, 2007, 7:47 pm

it cannot be reduced by any means, including a calculator that does symbolic calculus... if he says it can be done, fight the man :)

ordinarily with these you use something called synthetic divison, but for this specific one it doesn't work

for real?! it's on my problem set, i got two of the same things with different numbers... super confused... teacher prolly say oops my bad kids, i messed up this problem day its due :?

Re: Algebra 2 stuff

by raulperez » October 22nd, 2007, 7:22 pm

dude that's not even a factorable polynomial.... you've made some error in coming up with it

Algebra 2 stuff

by toadsdaki » October 22nd, 2007, 6:54 pm

Ok, so many of you will prolly say this is all basic stuff, but im comfused...

SO i have: 2x^3-7x^2-19x+35 and I need to factor this.. I can't just square root everything.... im confuzzled
