Ch 4 Quadratic Equations Pdf Quadratic Equation Mathematics A quadratic equation in the variable x is an equation of the form ax2 bx c = 0, where a, b, c are real numbers, a 0. for example, 2x2 x – 300 = 0 is a quadratic equation. ≠ similarly, 2x2 – 3x 1 = 0, 4x – 3x2 2 = 0 and 1 – x2 300 = 0 are also quadratic equations. in fact, any equation of the form p(x) = 0, where p(x) is a. In general, a real number is called a root of the quadratic equation ax2 bx c = 0, a 0 if a 2 b c = 0. we also say that x = is a solution of the quadratic equation, or that satisfies the quadratic equation. note that the zeroes of the quadratic polynomial ax2 bx c and the roots of the quadratic equation ax2 bx c = 0 are the same.
