Explanation:
~ First step to factorize numbers is to find the GCG, which in this case is 7, hence the we place the 7 outside the bracket.
~ Next you know that we have 42x we need to divide it by 7, this should give you 6x, now we have 7(6x
~ Now we do the same to 49, 49 divided by 7= 7
~ Hence this gives you the answer of 7(6x+7).
