Anyone in a calc class

[funk.]

for one, how do you factor 6x^2-5x-4

 

[Seths22]

you have to do a sign chart and all that homo shit. im tired so do it yourself

 

[user098123]

(2x+1)(3x-4). As for critical points, not exactly sure what you mean by that. Like, where the derivative is equal to 0? Because you would get 12x - 5 < 0 for your derivative, so your critical point would be at 5/12.

fack.

ehh thats not the right factors. and then you use the zeroes (critical points) like so. (-infinity, n1), (n1, n2), (n2, +infinity). and then find out if a number in each catagory fits. so basically i just need to factor the damn problem.

 

[funk.]

god damn it the original inequality is 6x^2-5x-4

 

[funk.]

i'm way too tired. it is (2x-1)(3x+4).

discriminant is 121

factors are -0.5 and 1.3333333

 

[user098123]

Actually it's not, that would give you 6x^2-3x+8x-4, or 6x^2+5x-4, and you said you wanted 6x^2-5x-4, right?

The factor for that is in my initial response, which is (2x+1)(3x-4). As for the critical points....I did that along time ago, I need to remember how to do them. If I can figure it out I'll let you know.

 

[funk.]

hahaha i'm so tired i wrote it wrong. OK. (2x+1)(3x-4) is right. sorry bout all that.

i swear to god. this kid does everyones homework if you post it on here. he's awesome.

 

[user098123]

It's how I pass the time as I slack on my own homework.

Speaking of which, if anyone can easily explain Green's Theorem in the Plane I would greatly appreciate it. So lost.

 

[Alex_G]

I'm so glad I dropped that class...Fuck AP's during senior year.

 

[Microcosm]

it's true you don't help out a lot so even though this isn't my thread karma + for you just because I have no idea what Green's theorem in the plane is and I can't help out.

so glad this site is constructive enough to offer math support. honestly this is sweet....

OMG me too that class kicked my dick
