The term "quadratic" comes from the Latin word "quadratus" meaning square, which refers to the fact that the variable x is squared in the equation. Did you know that when a rocket is launched, its path is described by a quadratic equation? Further, a quadratic equation has numerous applications in physics, engineering, astronomy, etc. Quadratic equations have maximum of two solutions, which can be real or complex numbers. We shall learn more about the roots of a quadratic equation in the below content.

Find the value of m for which the quadratic equation

Why is the restriction a! The simplest method of solving a quadratic equation, but one that is not always easily applied, is by factoring. This method depends on the following property. The next example shows how the zero-factor property is used to solve a quadratic equation. Check these solutions by substituting in the original equation. The next example shows how to write a quadratic equation in this form. Rewrite the equation so that the constant term is alone on one side of the equals sign. Square half the coefficient of x , and add this square to both sides of the equation. Factor the resulting trinomial as a perfect square and combine terms on the other side. This is how our quadratic equation step by step solver solves the problem above. You can see similar problems solved by clicking on 'Solve similar' button.

Find the value of m for which the quadratic equation

The quadratic equation will always have two roots. The nature of roots may be either real or imaginary. A quadratic polynomial, when equated to zero, becomes a quadratic equation. In other terms, a quadratic equation is a second degree algebraic equation. The values of x satisfying the equation are called the roots of the quadratic equation. The values of variables satisfying the given quadratic equation are called their roots. The term b 2 — 4ac in the quadratic formula is known as the discriminant of a quadratic equation.
