(x + 5)2
3y-6y in factored form = -3
when it is in its most reduced form.
64-x2 = (8-x)(8+x) when factored
When factored it is: 12(A+b)
ab(a - b)
you have to use F.O.I.L method to simplify it.
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.
(x + 5)2
You can't know if a general polynomial is in factored form.
3y-6y in factored form = -3

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).
It is equivalent to 3(4x+3y) 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
You multiply the factors.
