What is second-degree equation?

Answer 1

A second-degree equation, also known as a quadratic equation, is a polynomial equation of the form ( ax^2 + bx + c = 0 ), where ( a ), ( b ), and ( c ) are constants and ( a \neq 0 ). The highest exponent of the variable ( x ) is 2, which gives it its name. Quadratic equations can be solved using various methods, including factoring, completing the square, or applying the quadratic formula: ( x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} ). The solutions to a quadratic equation can be real or complex numbers, depending on the value of the discriminant ( b^2 - 4ac ).
