Solve the equation given by completing the square. If there are more than one answers, separate them by a comma. If there is no real solution, enter DNE (short for does not exist.)
Enter your answer as a list of values separated by commas: Example: -4, 3, 2 Enter each value as a number (like 5, -3, 2.2172) or as a calculation (like 5/3, 2^3, 5+4) Enter DNE for Does Not Exist, oo for Infinity
