Respuesta :

A because 6(2a) is 12a and 6(b) is 6b, your just multiplying the number outside the parentheses to the ones inside.

Answer:

6(2a+b)

Step-by-step explanation:

We are to factorise the given question

Which means we will have to determine what is common to both numbers

12a+6b

We can deduce that 6 is common to both

So let's factorise

6(2a+b)

Therefore the final answer is 6(2a+b)
