3x2-2x-21 = (3x+7)(x-3)
6x(3x2 - x + 4)
-(x + 2)(3x + 4)
Since 3x is a factor of 3x^2, it is automatically the GCF.
While it is possible to factor 3x2 from both of these and get 3x2(4 - 1), it's a lot easier to subtract 3x2 from 12x2 and get 9x2
factor out a 3x 3x(x-3)=3x2-9x
the answer is 3x2
-8x + 3x2 - 3
3x2 + 27x +60
You can take a 3x2 out of both of those, leaving 1 and 3x.
24x6 + 12x4 + 15x2 factor the greatest common factor, 3x2 = 3x2(8x4 + 4x2 + 5)
yes
3X2 + 6X + 9 3(X2 + 2 + 3) -----------------------3 is a common factor of all terms
x(3x-2)
2(3x2 - 2)
x(3x-4)
