D.4(2x - 3)(2x + 1)
3(x - 1)( x + 8)
You can use the formula for factoring the difference of two squares in this case.
A completely factored form is one which is composed of product of factors and can't be factorized further. Let us consider two examples: x2 - 4x + 4 is not a factored form because it can be factored as (x - 2)(x - 2). (x +1)(x2 - 4x + 4) is also not a factored form because x2 - 4x + 4 can be factored further as (x - 2)(x - 2). So, the completely factored form is (x + 1)(x - 2)(x - 2).
Five cubed in standard form is 53.
The number 6 can be factored into 2 x 3. So 6 cubed can be factored into 2 cubed times 3 cubed. In either case, the result is equal to 216.
It is 7*7*7.
5x5x5 5x5x5 5x5x5 5x5x5
2 x 2 x 2 = 8
64-x2 = (8-x)(8+x) when factored
6(2x - 3y)
6(u-14)
(4+x) (2x-3)
D.4(2x - 3)(2x + 1)
x(4x-2)
x2 - 2x = x(x - 2)
-83 is -512
