What is the quotient: (2x2 + 10x + 12) : (x + 3) ?

a. 2x + 6

b. 2x - 6

c. 2x + 4

d. 2x - 4, r = 1

The answer is C. Factor the equation: 2x^2 + 10x + 12 which gives you ... 2 (x + 2) (x + 3), and then cancel out (x + 3) because dividing (x + 3) by itself gives you one and the remaining term is 2 (x + 2) which is the same as 2x + 4.
