make x the subject of the formula?
2√(−x) − (r²−x) / r = 0
any help will be really appreciated!
Update:
sorry to the last poster I should have put brackets round √(−x)
making equation clearer:
2(√(−x)) − (r²−x) / r = 0

assuming the square root includes (-x)-r^2-x) I have concluded this:
2√(-x-r^2+x)/r ===> 2√(-r^2)/r ==> 2√(-1)(r^2)/r ===> 2r√(-1)
***:or if you know that √(-1)=i then the answer is just 2ri
