What is the common factor in 4x + 12 ?
And what is it called when you have three numbers, multiply the biggest with the smallest, the smallest by the biggest and the middle with itself and the answer is always 4 or something? Also why is that
In 4x + 12, both 4x and 12 are divisible by 4, so 4 is the common factor. One can factor 4x + 12 as 4*(x + 3).
I have no idea what you are on about in the rest of your question!
