Which of the binomials below is a factor of this trinomial?6x2 + 30x + 36A.x - 2B.x + 2C.x - 6D.x + 6SUBMITarrow_backPREVIOUS
Solution
To find out which binomial is a factor of the trinomial, we need to factorize the trinomial.
The trinomial is 6x^2 + 30x + 36.
First, we can take out the common factor which is 6.
So, 6x^2 + 30x + 36 = 6(x^2 + 5x + 6)
Now, we need to factorize the quadratic equation x^2 + 5x + 6.
We are looking for two numbers that multiply to 6 and add to 5.
Those numbers are 2 and 3.
So, x^2 + 5x + 6 = (x + 2)(x + 3)
Therefore, the factors of the trinomial 6x^2 + 30x + 36 are 6, (x + 2) and (x + 3).
So, the binomial x + 2 is a factor of the trinomial.
Therefore, the answer is B. x + 2.
