Im assuming the "6x2" is supposed to be 6x squared. The factored form would be (2x+1) (3x-8)
(2x - 3)*(4x2 + 6x + 9) = 0
(2x+1)(x+2) = 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
y = 3x + 21x2 = 3x(1 + 7x)
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).
r2-r-56 factored out equals (r-8)(r+7).
It cannot be factored.
2(a+b) is 2a plus 2b in factored form.
The factor pair is (2,10)
