Answer:
8(2x+7)
Step-by-step explanation:
Factoring involves breaking down an expression until it can no longer be broken down. In this instance, 16 and 56 have the factor 8 (meaning multiplying 8 with another number will result in either 16 or 54). If we were to factor out 8 from 16, then we would get 2 (because 2 x 8 = 16) and if we factored out 8 from 56, then we would get 7 (because 7 x 8 = 56).
8 is a factor for both of these numbers, thus it will be distributed to both, so we can now convert 16x + 56 to 8(2x+7).
