(2x - 1)(4x2 + 2x + 1)
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
The GCF is 4x2.
The GCF is 2x3
3(8x + 1)(8x - 1)
Take out the common factor, 3: 3x + 6 = 3(x + 2).
x(7x ^2 - 4x + 8)
(2x - 1)(2x + 5)
4(x^2 + 8x + 160)
(2x - y2)(4x2 + 2xy2 + y4)
(2x - 1)(4x2 + 2x + 1)
(2x + 5)(4x2 - 10x + 25)
4(x^2 + 2x - 5)
4(x + 1)(x + 1)
4(x^2 + 2x + 8)
4x2-8x-5 (2x+1)(2x-5)
If that's - 8x - 5, the answer is (2x + 1)(2x - 5). If that's + 8x + 5, it gets ugly in a hurry.
