Factoring Trinomials: Would This Be The Correct Answer To 3x^2-7x+2? Answer: 3x(1x-2) (-1x+2)

Question

anonymous · Answer

No, (3x-1)(x-2) is the correct answer. Do you want me to show you how to get the correct answer?

anonymous · Answer

PLEASE! Thank You!

anonymous · Answer

Yep :) ok, so first what are the factors of 3?

anonymous · Answer

3 and 1

anonymous · Answer

Wouldn't You Do The Factors Of 6 Though?

anonymous · Answer

good :) but no because we are trying to find what equals 3x^2 , not the result of 3 times x to the second power, does that make sense?

anonymous · Answer

you are right but we are trying to find the factors of 6

anonymous · Answer

Yes :)

anonymous · Answer

*aren't lol sorry

anonymous · Answer

anyway 3 and 1 are the first terms in our set of parentheses (3x    )(1x    ) or (1x    )(3x    )

anonymous · Answer

since there aren't another pair of factors to use

anonymous · Answer

Okay :)

anonymous · Answer

ok :) so now you look at the last term of the trinomial that was given to you, in this case it is 2, right?

anonymous · Answer

Yes 2.

anonymous · Answer

now what are the factors of 2? haha :)

anonymous · Answer

2 and 1 :P

anonymous · Answer

:) yep which means those are our second terms giving us either (   2)(   1) or 
(     1)(     2) :) and since the last term is a positive it means that the signs will be the same, either -,- or +,+

anonymous · Answer

so from now on it is guess and check (which won't be hard if you can do mental multiplication well) and back to the 3x and 1x which term do you want to go here, |dw:1393544464732:dw|
