What is difference between an algorithm and a flow chart? Draw a flowchart for a quadratic equation?
Note that: For solving a quadratic formula we are using the following formulas respectively.
(General formula for a quadratic equation)
1. Step:
2. Find the constants of the given equation.
a = 1, b = 2 and c = -3
3. Calculate the discriminant:
=
4. If d ˃ = 0, we have two real roots which can be calculated with following formulas:
5. If d˂ 0, this equation does not have real roots.
Draw a flow chart.
Write a program in Java to calculate a given quadratic equation using above steps.
