    explain the intuition as to why you breakdown 12 into 8+4 without referring to the correct answer. in order to do maths properly people need to solve for answers they dont already know what they are. explain the intuition as to why you would randomly breadown 12 into 8+4 if you had no idea that that idea would lead to to the correct answer

      I followed the powers of x, 8 = 2³, we have x³, then l realized that we can make use of difference of two cubes formula, again, 4 = 2², we have x², of which we can use difference of two squares formula
