Question

which of the following expressions cannot be factored?
A. 15x-10
B. 4x+8
C. 3x+8
D. 2x-2

Answer 1

Answer:

C. 3x + 8

Step-by-step explanation:

A. can be factored; Factor 5 from all terms:

(15x - 10)/5 = 3x - 2

B. can be factored; Factor 4 from all terms:

(4x + 8)/4 = x + 2

D. can be factored; Factor 2 from all terms:

(2x - 2)/2 = x - 1
