### What is Meant by Roots?

In mathematics, the roots generally define the roots/variable value of the quadratic equation. We know that the equation with a higher degree of two is called the quadratic equation. The equation should be of the form ax2 + bx+ c = 0. Here a, b, and c are the coefficients of the equation and the value of a should not be equal to 0, and x is the variable. The solution obtained for the value of x is called the roots of the quadratic equation. The root values can be usually obtained using the formula,

$$x= \frac{-b\pm \sqrt{b^{2}-4ac}}{2a}$$
