### In mathematics, roots are the values that make an equation or expression equal to zero

In mathematics, roots are the values that make an equation or expression equal to zero. More specifically, if you have an equation of the form f(x) = 0, then the roots or solutions of the equation are the values of x for which the equation holds true.

For example, consider the equation x^2 – 4 = 0. To find the roots of this equation, we set it equal to zero and solve for x. In this case, we can rewrite the equation as x^2 = 4. Taking the square root of both sides, we find x = ±2. Therefore, the roots of the equation x^2 – 4 = 0 are x = 2 and x = -2.

Roots can also be represented graphically as the points where a function intersects the x-axis. If a function f(x) intersects the x-axis at point (a,0), then the value a is a root of the equation f(x) = 0.

It’s important to note that some equations may have multiple roots, some may have no roots, and some may have complex roots (involving imaginary numbers). Additionally, roots can be real or non-real, depending on the nature of the equation.

Roots are a fundamental concept in various branches of mathematics, including algebra, calculus, and complex analysis. They have applications in solving equations, analyzing functions and their behavior, and understanding the characteristics of mathematical models.
