The GCF is 4x2.
X3 - 4X2 - 45XX(X2 - 4X - 45)=============X is only common factor here.
If you mean: 4x squared+12x-40 then it is (x+5)(x-2) after dividing all terms by 4
If that's + 4x2, the answer is 2x(x2 + 2x - 4)
Operational signs would make this a lot easier. Assuming that's + 12x + 5, the answer is (2x + 1)(2x + 5)
The GCF is 4x2.
12x * 4x2 = 48x3
The GCF is 4.
2(4x2 + 6x - 1)
4(x + 2)(x + 1)
Notice that we can factor out 2x from both terms on the LH side: ... 4x2+6x=0. The greatest common factor of 4 and 6 is 2 . The greatest common factor of x2 and x ...
(2x + 3)(2x + 3)
4x2 + 12x + 5 = (2x + 1)(2x + 5).
24x6 + 12x4 + 15x2 factor the greatest common factor, 3x2 = 3x2(8x4 + 4x2 + 5)
2: 2x2=4 , 4x2=8, 12x2=24
4x2 = -12x, divide both sides by 4x: x = -3
4x2+12x = 4x(x+3) when factored
