3 * x * x * y
3x2-9x-30 =3x2+6x-15x-30 =3x(x+2)-15(x+2) =(3x-15)(x+2) OR 3(x - 5)(x+2)
(3x+1)(x+2)
3x2 + 6x is ONE expression. A common factor is a factor that is COMMON to two (or more) expressions - not just one. An alternative answer: 3x can be factored out of both of those.
(3x + 1)(x + 6)
x3 - 3x2 + x - 3 = (x2 +1)( x - 3)
21x3-35x2+14x = 7x(3x2-5x+2)
The degree of this polynomial is 2.
If that's 3x2 + 7x + 2, the answer is (x + 2)(3x + 1)
(x + 2)(3x + 1)
3x2 + 27x +60
3x2 - 5x - 2 can be factored into (3x + 1) (x - 2)
It is a second degree polynomial.
-7
(x2 + 1)(x - 3)
3x2 + 33x + 54 =3(x2 + 11x + 18) = 3(x + 9)(x + 2)
3x2-7x-20 = (3x+5)(x-4) when factored
