Q:# What does quadratic mean?

A:### Quick Answer

According to Dictionary.com, the word "quadratic" is derived from the Latin word "quadratus" and means "square." In math, a quadratic refers to a polynomial where the highest degree of the term is two, which means the largest term in the polynomial is squared or raised to the second power.

Know MoreOne well-known application of quadratics is the quadratic formula. It is used to determine the roots of a quadratic equation. The roots can be thought of as the places where the quadratic equation equals zero and can be either real or complex numbers.

When graphed on a coordinate plane, a quadratic will take the shape of a parabola.

## Who invented the quadratic equation?

A:Babylonian mathematicians as early as the Sumerian Ur III period (21st to 20th century B.C.) used geometric methods to solve second-degree problems. Similar geometric methods solved quadratic equations in later Babylonia, Egypt, Greece, China, and India. Indian mathematician Brahmagupta (597-668 C.E.) was the first to give an explicit solution.

## How do you solve quadratic equations by factoring?

A:To solve quadratic equations by factoring, it's a matter of finding the x-intercepts of the graph, or the point at which the graph crosses the x-axis. Quadratics are in the form of ax^2 + bx + c = 0, so you have to simplify the equation into simple binomials.

## How do you solve quadratic inequalities?

A:To solve a quadratic inequality, find the coordinates where the graph crosses the x axis, and determine the direction for the parabola. Complete the parabola through the points and shade the appropriate points to express the solution graphically.
