A quadratic is a type of mathematical expression or equation that involves a variable raised to the power of 2, such as ???? ???? 2 + ???? ???? + ???? ax 2 +bx+c, where ???? a, ???? b, and ???? c are constants, and ???? ≠ 0 a ? =0. Quadratics are common in algebra and appear in various scenarios, including physics and engineering. The graph of a quadratic equation forms a parabola, which can open upwards or downwards depending on the sign of ???? a. Quadratic equations are solved using methods like factoring, completing the square, or the quadratic formula, ???? = − ???? ± ???? 2 − 4 ???? ???? 2 ???? x= 2a −b± b 2 −4ac ? ? .
