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).
a3-4a = a(a2-4) when factored
2(a+b) is 2a plus 2b in factored form.
If you mean 4y+10 then it is 2(2y+5) when factored
It is (x+4)(x+5) when factored
"(x - 5)(x - 2)"
27-y3 factored completely = 24
When the expression is broken down into its prime factors it is factored completely.
6x5(x2 - 6x + 3)
a3-4a = a(a2-4) when factored
You can convert standard form to factored form by using a factoring tree to convert to the long-form factored format. You can also work backwards to convert from factored to standard form.
You can't know if a general polynomial is in factored form.
3y-6y in factored form = -3
If you mean: y2+5y+6 then it is (y+2)(y+3) when factored completely
2(2x + 5)(2x - 5)
6x5(x2 - 6x + 3)
