Find the factorization of the polynomial below.

3x²+10x+3

A. (3x+1) (x+3)

B. (3x+2) (x+2)

C. (3x+2) (x+3)

D. (3x+1) (x+2)

One of the simplest ways is to find the last number as it isn't a coefficient of X

You can find it by multiplying the 2 numbers in the bracket without X. E. G the 1 from (3x+1) and the 3 from (x+3)

so we're looking for 3 as it isn't a coefficient of X

for A, (1x3) = 3

For B (2x2) = 4

for C (2x3) = 6

For D (1X2) = 2

so the answer is A
