How do i factorise 20 + 10x?

Firstly, we can take a look at the degree x's in each term. It seems like they share a common degree of 0. In other words, we will not be able to factor out the x's in the expression.

Secondly, we need to find out if we can factor out a number out of the expression. Therefore we can identify that 10 is a common factor of both terms. So we will be able to factor out 10 from the expression to get 10(2 + x).
