No. While x/x can equal one, since anything divided by itself will give you 1, You’re left with 1+6, not 1/6.
No, it does not.
x and x + 6 are both prime and cannot be factored.
There are no common factors to divide out.
x over x + 6 is already simplified.
If you substitute in a value for x, the fraction will not be equal to 1/6.
