FAQs

Question: What is the quadratic formula?
Answer: The quadratic formula is used to find the roots of a quadratic equation and is given by x = (-b ± √(b² - 4ac)) / 2a.

Question: How do I determine the nature of the roots of a quadratic equation?
Answer: The nature of the roots can be determined using the discriminant (D = b² - 4ac). If D > 0, there are two distinct real roots; if D = 0, there is one real root; and if D < 0, the roots are complex.
