4x
X3 - 4X2 - 45XX(X2 - 4X - 45)=============X is only common factor here.
If that's + 4x2, the answer is 2x(x2 + 2x - 4)
4x2+20x+25 (2x+5)^2
Make a factor-tree and the look for the matches of their prime factorization... Using 6 and 8: 6......... 8 2x3.....4x2 .........2x2 so the prime factorization of 6 is 2x3 and 8 is 2x2x2 so the only match you have is two so the gcf of 6 and 8 is 2
4x
The GCF is 4.
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 ...
24x6 + 12x4 + 15x2 factor the greatest common factor, 3x2 = 3x2(8x4 + 4x2 + 5)
2: 2x2=4 , 4x2=8, 12x2=24
Take out the common factor, which in this case is 4x2. Divide each of the terms by this common factor. 12x2 - 4x3 = 4x2(3+x)
X3 - 4X2 - 45XX(X2 - 4X - 45)=============X is only common factor here.
4x2 - 9y Not factorable from what I see.
5x is a common factor of all terms:- 5x(x3+4x2+9)
4x2-y2 = (2x-y)(2x+y)
The Greatest Common Factor of 4, 8, and 16 is 4. This is because 4x1=4, 4x2=8, and 4x4=16. No higher number can be multiplied into all three of these numbers.
If that's + 4x2, the answer is 2x(x2 + 2x - 4)
