Every Quadratic equation has two roots. And
this program is implemented to find the roots of the entered
quadratic equation.
Logic : The roots of any
quadratic equation of the the form,
are,
The same equation is computerized here. The
program asks user to enter the three coefficients a, b and c.
Then it finds out numerator- which is the discriminate,
and the denominator of the equation of the roots. Then it
checks if the numerator is greater, equals or less than zero.
Prints out the results according to the situation.
This can be elaborated to find the roots of
equation with higher powers. You are pleased to contact us
with your doubts through the
discussion forum.
