FAQs

Question: What is the quadratic formula?
Answer: The quadratic formula is given by x = (-b ± √(b² - 4ac)) / (2a), which is used to find the roots of a quadratic equation ax² + bx + c = 0.

Question: How can 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, the roots are real and distinct; if D = 0, the roots are real and equal; and if D < 0, the roots are complex.
