You can't know if a general polynomial is in factored form.
You multiply the factors.
2x + 3 can be factored as follows: 2(x + 1.5)
2a^3 + 54 can first be factored into 2 (a^3 + 27). This can then be factored out to 2 (a + 3) (a^2 - 3a + 9).
It is 7*7*7.
27-y3 factored completely = 24
27
(2x - 3)*(4x2 + 6x + 9) = 0
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
It is: 3*3*3 = 27
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).
8/27 is in simplest form since 27 does not go into 8. The easy way to write a fraction is simplest form is to write the numerator and the denominator in factored form, cancel out all the common prime factors and then multiply the what is left. So 8/27= 2x2x2/3x3x3 and we see there are no common prime factors so it is already in simplest form.
2(a+b) is 2a plus 2b in factored form.
If you mean 4y+10 then it is 2(2y+5) when factored
