Dear amrit,

Consider the quadratic equation

displaymath22

A real number x will be called a solution or a root if it satisfies the equation, meaning tex2html_wrap_inline26 . It is easy to see that the roots are exactly the x-intercepts of the quadratic function tex2html_wrap_inline28 , that is the intersection between the graph of the quadratic function with the x-axis.
