Determine which of the following is true for the expression 2 x 2 + 12 x + 18.
A. The expression is prime.
B. Two can be factored from each term in the trinomial to generate 2( x 2 + 6 x + 9), and no more factoring can be done.
C. Two can be factored from each term in the trinomial to generate 2(x 2 + 6 x + 9), and the resulting trinomial can be factored to generate 2( x + 3) 2 .
D. The trinomial 2 x 2 + 12 x + 18 is equivalent to (x + 3) 2 .
