not sure 100% but my dad told me:
e.g. 2(3x + 4)
2 x 3x = 6x
2 x 4 = 8
so its
6x + 8
another one is
x(7x + x^2)
x times 7x = 7x^2
x times x^2 = x^3
so its
7x^2 + x^3
PS. the ^2 and ^3 stands for sqaured and cubed (:

Is there a math problem that cannot be solved by completing the square?
If you aren't dealing with algebra, such as x2+3x+21, then completing the square wont be able to solve the porblem, however if you are using algebra, and you cannot factorise, then completing the square will always work

How do you factor 16x2-225?
You need to spot that 16x2 is the square of 4x and that 225 is the square of 15. Notice that the expression is a "difference of 2 squares", which is a standard result in algebra a2 - b2 = (a + b)(a - b) so here we factorise to (4x + 15)(4x - 15)
