we use 1,2,3,...,9 whats this problem anser ? 1/(x*x)+x/(x*x)+x/(x*x)=1
If you can only use the whole numbers from 1 through 9 to solve that problem, you won't get an answer.
1/x² + 1/x + 1/x = 1
1/x² + 2/x = 1
1 + 2x = x² (multiplying both sides by x²)
0 = x² - 2x - 1
x = 1 ± √2 (using quadratic formula)
Nice analysis there, geno........!!!!
