3x2 + 36x + 81 = 3(x2 + 13x + 27)
3x2 + 36x + 81 = 3(x2 + 12x + 27) = 3(x + 3)(x + 9), which are its prime factors; or, if you prefer, 3x2 + 36x + 81 = (3x + 9)(x + 9), which is also accurate. You may easily verify these results by multiplying back.
3x2 + 33x + 54 =3(x2 + 11x + 18) = 3(x + 9)(x + 2)
(x + 2)(3x + 1)
The degree of this polynomial is 2.
(3X + 9) (X + 9)
3x2 + 10x + 3 = (x + 3)(3x + 1).
It is a second degree polynomial.
x3 - 3x2 + x - 3 = (x2 +1)( x - 3)
