12x4 - 42x6 = 6x4 (2 - 7x2)

The GCF is 4x4
If you want to do 12x4 and a half, you have to do 12 times 4. It is equal to 12+12+12+12. That would be 48. Next, the "half". Half means it is divided in 2. And would be 0.5. If you add 48 and 0.5, it would be 48.5. I wish this would be a great help :)
Put 12 over 49 then multiply 12x9 then under that put a 0 then do 12x4
12x4 - 42x6 = 6x4 (2 - 7x2)
48
24x6 + 12x4 + 15x2 factor the greatest common factor, 3x2 = 3x2(8x4 + 4x2 + 5)

12 x 4 = 48

The GCF is 4x4
The GCF is 4x4
The GCF is 6x3.
It is probably 2.
4 -apex~
use the difference of two squares yule.
