Question

Which of the binomials below is a factor of this trinomial?

3x2 + 19x + 6

Answer 1

3x2 + 19x + 6
= (3x + 1)(x + 6)

Answer 2

How did you get that?

Answer 3

to get 3x^2 you have to have
(3x )(x )

now for the other numbers in the parentheses we need 2 numbers whose product is + 6
and when one of them is multiplied by 3 and added to the other gives + 19

these are +6 and + 1

1 + 6 = 6
and
3*6 + 1 = 19
