Which expression is the factored form of 23x+423x+4?

a. 23 (x+12) 23 (x+12)

b. 23 (x+6) 23 (x+6)

c. 23 (x+4) 23 (x+4)

d. 13 (2x+6)

23x + 4

The expression is not factorable since the the factor of 23 = 23x1 only

Maybe the expression is wrong

Maybe its 24x + 4

Which the factor is 4

In factor form

24xx + 4, factor out 4

4 (6x + 1)
