Answer:
x + 6.
Step-by-step explanation:
2x + 12
= 2(x + 6)
x^2 + 7x + 6
= (x + 6)(x + 1)
(x + 6) is common to both factors so that is the answer.
C. x + 6
Start by factoring completely the numerator and the denominator.
2x + 12 = 2(x + 6)
x^2 + 7x + 6 = (x + 1)(x + 6)
The only common factor is x + 6, so the GCF is x + 6
Just solve.
