FAQs

Question: What is the standard form of a quadratic equation?
Answer: The standard form of a quadratic equation is ax² + bx + c = 0, where a, b, and c are constants and a ≠ 0.

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.
