Re-post so we know what the actual expression is:

z1^2+z2/z2+z3 = z1%5E2%2Bz2%2Fz2%2Bz3?

or

(z1^2+z2)/(z2+z3) = %28z1%5E2%2Bz2%29%2F%28z2%2Bz3%29?

If you are working on problems like this, then your mathematical knowledge should be ample for you to know that proper use of parentheses is important....
