Question

Factorise (2ab-4bc)?

Answer 1

2b(a-2c)

because 2 and b are common in both parts therefore you put these two before the bracket and then in the bracket is whatever you need to make the rest of the sum, for example the 2b combined with the first section which is a will make 2ab and the 2b when timesed by 2c will make 4bc, hope this helps!
