Which of the binomials below is a factor of this trinomial? 4x2 + 12x + 9

A. 2x + 1
B. 2x-3
C. 2x + 3
D. 2x-1

i think its 2x+1

Step-by-step explanation:

1 Split the second term in 2{x}^{2}-5x-32x  

2

−5x−3 into two terms.

2{x}^{2}+x-6x-3

2x  

2

+x−6x−3

2 Factor out common terms in the first two terms, then in the last two terms.

x(2x+1)-3(2x+1)

x(2x+1)−3(2x+1)

3 Factor out the common term 2x+12x+1.

(2x+1)(x-3)

(2x+1)(x−3)

Done

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.
