Question

Factor the expression 27a + 3 using the GCF.

O 3a(9-1)
O 3(3+1)
O 319a+1)
O 9(3a-1)

Answer 1

Answer: 3(9a+1)
Steps:
3 x 9a = 27a
3 x 1 = 3
27a + 3

Answer 2

C

Explanation:

The greatest common factor must be a number smaller than or equal to the largest coefficient (in this case 27 and it must be smaller than 27) and equal to or smaller than the smallest coefficient (in this case 3 and it is equal to 3).

GCF = 3

3(9a + 1)

which is C
