Which of the binomials below is a factor of this trinomial? (pls answer soon as possible)6x^2+30x+36 a. x+2 b. x-6 c. x-2 d. x+6

The first thing I would do would be to factor 6 out of 6x^2+30x+36.  You should get

x^2 + 5x + 6.  

Factoring this result is straightforward, since we see immediately that 2 and 3 are factors of 6, and that 2+3 = 5 (coeff. of the middle term).

A. x+2
B.x-6 
C.x-2
D. x+6

From the above discussion, I see immediately that x-2 is a factor of the given trinomial.  x-2 corresponds to the root 2, whereas x+2 corresponds to the root -2 (which does not belong here).
