The answer to this depends on what you mean by "x 7" If you mean: x2 -7x, then it can be factored out as x(x - 7) If you mean: x2 - x7, then you can factor it out as: x2(1 - x5) If you mean: x2 - x + 7, then it can not be factored If you mean: (x2 - x)7, then the inner term can be factored, giving you (x[x - 1])7 If you mean something else, then you will need to be more clear with your question.
x2-6x+8 = (x-2)(x-4) when factored
x2+7x-18 = (x+9)(x-2) when factored
If you mean x2 + 2x + 15: Then the answer would be that it's a quadratic expression with no factors. If you mean x2 - 2x + 15: Then it can be factored out to: (x - 5)(x + 3) If you mean x2 + 2x - 15: Then it can be factored out to: (x + 5)(x - 3)
X2 - 8X + 15 = (X - 3)(X - 5)
It is (x-1)(x-1) when factored
x2 + 1 can't be factored in the real numbers. If complex numbers are acceptable, it can be factored as (x + i)(x - i).
If you mean: x2+3x+2 then it is (x+1)(x+2) when factored
x2+x-6 = (x-2)(x+3) when factored

x2-7x+6 = (x-1)(x-6) when factored.
x2+16x-17 = (x-1)(x+17) when factored
The answer to this depends on what you mean by "x 7" If you mean: x2 -7x, then it can be factored out as x(x - 7) If you mean: x2 - x7, then you can factor it out as: x2(1 - x5) If you mean: x2 - x + 7, then it can not be factored If you mean: (x2 - x)7, then the inner term can be factored, giving you (x[x - 1])7 If you mean something else, then you will need to be more clear with your question.
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).
x2-6x+8 = (x-2)(x-4) when factored
x3 - x2 + 2x = x*(x2 - x + 2) which cannot be factored further.
x2+10x-24 = (x-2)(x+12) when factored
