You can put this solution on YOUR website!
x>0 will do, since the sides of the triangle cannot be negative. In addition, the values of x must NEVER cause a denominator to be zero, which means that ALSO, x cannot be 0, -1, or -2. However, if you select x>0, you have eliminated these problems as well.
