## mikaa_toxica13 2 years ago What are the factors of 3x2 + 10x + 3? (3x − 1)(x − 3) (3x − 3)(x − 1) (3x + 1)(x + 3)<---answer (3x + 3)(x + 1)

1. mikaa_toxica13

okay wel what then

2. ryan123345

foil them and see which one matches

3. mikaa_toxica13

well its either B or C

4. mikaa_toxica13

okay well how about u explain it and tell me what it is.

5. ryan123345

You were right lol. I just had to do it on a piece of paper. Sorry

6. mikaa_toxica13

14. ryan123345

or you can just factor it

15. aajugdar

hehe

16. aajugdar

what if they tell just to factorize without options

17. ryan123345

she should have learned that in class...

18. aajugdar

hmm,well ok i will type that out

19. ryan123345

type what out?

20. mikaa_toxica13

well maybe i have a crappy teacher -_-

21. aajugdar

factors

22. mikaa_toxica13

which choice would be the answer ?

23. ryan123345

you got it right... It would be c

24. mikaa_toxica13

u said earlier it wasnt c. -_-

25. aajugdar

hold on

26. aajugdar

\[3x^2+10x+3\] now multiply \[x^2\] coefficient 3 to the final 3 you will get 9 so split 10x in such a way that you get their multiplication 9 so 9*1 =9 and 9+1 =10 so we write equation as \[3x^2+9x+x+3\] now take 3x common \[3x(x+3)+1(x+3)\] which gives you \[(x+3)(3x+1)\]

27. aajugdar

i hope you got it

28. mikaa_toxica13

i think so :)

29. aajugdar

good :P
