All of these solutions are complex numbers, which means the equation has imaginary roots. Complex numbers are written in the form of a+bi, where a is a real number and bi represents the imaginary number. For quadratic equations, complex roots are often also complex conjugates. This means that the solution is x=a<u>+</u>bi, so to find the other conjugate simply switch the sign. For example, if x=5-4i is a solution, so is x=5+4i.
