Question

The discriminant of a function is -63, state the number and type of solutions:

Answer 1

• Two imaginary solutions

-----------------------

Number of solutions depending on the value of the discriminant:

• D > 0, two real solutions;
• D = 0, one real solution;
• D < 0, two imaginary solutions.

Since we have d = - 63 < 0, the equation has two imaginary solutions.
