Question

what is meant by Root in quadratic equation

Answer 1

Answer:

Roots are also called x-intercepts or zeros. A quadratic function is graphically represented by a parabola with vertex located at the origin, below the x-axis, or above the x-axis. Therefore, a quadratic function may have one, two, or zero roots.

Answer 2

Answer:

Consider the quadratic equation ax
$ax ^{2} + bx + c = 0$

A real number x will be called a solution or a root if it satisfies the equation, meaning
$ax ^{2} + bx + c = 0$
 . It is easy to see that the roots are exactly the x-intercepts of the quadratic function 
$f(x) = ax^{2} + bx + c = 0$
 , that is the intersection between the graph of the quadratic function with the x-axis.
