Concise Selina Solutions for Class 10 maths Chapter 5 Quadratic Equations
An equation with one variable, in which the highest power of the variable is two, is known as the quadratic equation. In algebra, a quadratic equation is an equation that can be rearranged in standard form as where x represents an unknown, and a, b, and c represent known numbers, where a is not equal 0. If a = 0, then the equation is linear, not quadratic, as there is no term. Any equation containing one term in which the unknown is squared and no term in which it is raised to a higher power solve for x in the quadratic equation x2 + 4x + 4 = 0. In mathematics, a quadratic is a type of problem that deals with a variable multiplied by itself - an operation known as squares. This language derives from the area of a square is its side length multiplied by itself. The word "quadratic" comes from quadratum, the Latin word for square. Quadratic equations are used in everyday life, as when calculating areas, determining a product's profit or formulating the speed of an object. Quadratic equations refer to equations with at least one squared variable, with the most standard form being ax² + bx + c = 0.
The quadratic equation is used to find the curve on a Cartesian grid. It is primarily used to find the curve that objects take when they fly through the air - for example, a softball, tennis ball, football, baseball, soccer ball, basketball, etc.
