Identify the factors of 3a2 + a − 14. Need to know how to do this.

OpenStudy (ashleyisakitty):

Do you know how to factor at all? The FOIL method can help. Do you have multiple choices with this ja1?

OpenStudy (ja1):

Yes I know how to do most but I didn't get the right answeer when i did

OpenStudy (ja1):

(3a + 7)(a − 2) (3a − 7)(a + 2) (3a + 14)(a − 1) (3a − 14)(a + 1)

OpenStudy (ja1):

I know for a fact that B and D are out

OpenStudy (ashleyisakitty):

The answer is A! Foil it back and youd get 3a^2 -6a + 7a -14. B would be 3a^2 +6a -7a -14 C would be 3a^2 -3a +14a -14 and D would have been 3a^2 +3a -14a -14 .

OpenStudy (ja1):

woh i got all that but where did you get 6a?

OpenStudy (ja1):

OpenStudy (ja1):

3a² * - 2 = -6a
