Im having trouble factorising: (x/(16 + x²)^½) - 1/3 = 0 Thats the square root of (16+x*x) divided by x, minus 1/3. I have to find the values that make it equal 0. Can someone please help me? Thanks!

How did you get the equation over 9 in step 3? and how did you get the equation to equal x-squared?
