Question

Which of the following trinomials can be factored?
a. 3b2+4b+1
b.3b2+6b+14
c. 3b2+8b+1
d. 3b2+30b+2

Please show the work on how you got it factored.
Thank you

Answer 1

any of them can be run thru the quadratic formula; what defines a factoring?

Answer 2

3.2 = 6; and i cant see and factors of 6 that add up to 30

Answer 3

or 8

Answer 4

a looks good for it tho

Answer 5

and b maybe

Answer 6

yeah a is correct but can u show me how u factor it.
Thanks tips

Answer 7

3.1 = 3

3+1 = 4

(x+3)(x+1)

Answer 8

forgot to divide out the 3 again

Answer 9

(x+3/3)(x+1/3)

(x+1)(3x+1)

Answer 10

thats better

Answer 11

(x /3)(x /3)

3b2+6b+14

3(14) = 42 i dont think factors of 42 will add to get 6

Answer 12

5.1=5
4.2=8
3.3=9

none of which are 42

Answer 13

so i think a is the only factorable one

Answer 14

so the answer would be
(x+1)(3x+1) then?

Answer 15

yes, for "a"
