How do I factorise 12y-18

When we factorise we basically want to put an equation into brackets.Firstly we need to see what can be taken out of both parts of the equation.Both 12 and 18 divide by 6. 12/6= 2 and 18/6 = 3So we can take 6 out and put it outside the bracket and have 2y and 3 on the inside.6(2y-3)
