(x + 5)(x + 2)
It is: (x+1)(x+6) when factored
That would be -2 (x-2) x (x+3). Click on the Wolfram|Alpha link for all of your polynomial factorization needs.
x3 - 7x2 + 6x =x (x2 - 7x + 6) =x (x - 6) (x - 1)
The actual equation itself is the polynomial. There is no polynomial for it, and your question doesn't really make sense.
It is (x+2)(x+9) when factored
(x + 2)(3x + 1)
It is 6x(2x+5) when factored
(x + 5)(x + 2)
x3 - 12x2 + 35x = x (x2 - 12x + 35) = x (x - 7) (x - 5)
x² + 8x + 15 = (x + 5)(x + 3)
x + 12x + 20 = (x + 10)(x + 2)

88 -Apex ;)
3x2 + 33x + 54 =3(x2 + 11x + 18) = 3(x + 9)(x + 2)
