Factor completely -6x2 + 18x – 24.
nikato
  • nikato
look at 6, 18, and 24. what can divide all 3 numbers?
anonymous
  • anonymous
24x2

By 3 and 6
anonymous
  • anonymous
But the 6 is a negative, so would it be -3 and -6?
anonymous
  • anonymous
yes
nikato
  • nikato
yes. lets use the bigger one. you what do you get if you factor out a 6?
anonymous
  • anonymous
answer is 6(x-4)
anonymous
  • anonymous
@asianswag thats not one of the answers :( and besides, I want to learn how to do this, not just get an answer
anonymous
  • anonymous
okay sorry
anonymous
  • anonymous
It's alright.
anonymous
  • anonymous
also is it -6x^2+18x-24?
anonymous
  • anonymous
the question?
anonymous
  • anonymous
Correct. Should I put the ^ symbol from now on?
anonymous
  • anonymous
yes
nikato
  • nikato
|dw:1433969339807:dw| ok?
anonymous
  • anonymous
yes that was my mistake
anonymous
  • anonymous
Alright, well this is getting confusing. I wanna focus on the help of one person so I'm gonna focus on nikato for now. Hope you guys understand
anonymous
  • anonymous
Okay, nikato
anonymous
  • anonymous
ok
anonymous
  • anonymous
okay goodluck
anonymous
  • anonymous
Thank you, and thanks for understanding
nikato
  • nikato
ok. now lets look at what's inside the paranthese, do you know how to factor that?
anonymous
  • anonymous
Yeah, give me a sec
anonymous
  • anonymous
I got -6x^2+18x-24
anonymous
  • anonymous
Sorry it took so long, had to find a pencil and paper
nikato
  • nikato
wait, i think you did the oppsite. i think you distributed instead of factoring. you have something that looks like -6(x-__)(x+__)
anonymous
  • anonymous
Ooooh, alright. Haha, sorry I get confused by the two. How would I factor then?
nikato
  • nikato
|dw:1433970053677:dw| to factor this, you want to find two numbers when multiply gives you AC, but when you add them, you get B
nikato
  • nikato
so in this case, you're looking for two numbers that multiply to give you 4, but when you add them, you'll get -3
anonymous
  • anonymous
OOOOOH -4 and 1?
anonymous
  • anonymous
That took me so long to get I feel so stupid right now XD
nikato
  • nikato
yea. and because there's A=1. you dont have to worry about coefficients. so the factored form of x^2-3x+4= (x-4)(x+1)
nikato
  • nikato
wait, is you problem right? are you sure it's not +24
anonymous
  • anonymous
Yup, I'm positive. -6x^2 +18 - 24
nikato
  • nikato
oops. but i dont think you have factor it to (x-4)(x+1) because if you FOIL and check it you have x^2-3x-4., but you want +4 so this doesnt work so the most you can factor up to is -6(x^2 -3x +4)
anonymous
  • anonymous
Oh, okay. I see how you got that. Yeah, thats one of the answer choices. Thank you for your help! Since you spent 30 minutes trying to help me out I'll give you a medal AND fan!
nikato
  • nikato
yea. sorry for wasting your time. should've done it ahead of time. but you learned how to check it.
anonymous
  • anonymous
Nah its alright, you didn't waste any time. I just wanted to know how to do this, but the lesson wasn't very clear in my opinion. Thanks for the help :D
