If discriminant = 0, then just find root1=root2= -b/2*a and print both roots are real and equal.Ħ.

If discriminant > 0, find both the roots via formulas expressed in the program i.e.ĥ. Find the discriminant value using the formula : disc = b * b – 4 * a * c.Ĥ. Root1 (-y + sqrt(det)) / (2 x) Else if (discriminant 0) then, Root1. Otherwise, we’ll find the discriminant.ģ. Steps to find the square roots of the quadratic equation If discriminant > 0, then. In that case, we simply terminate the program with a return statement. If a=0, the equation cannot be a quadratic equation since a quadratic equation has degree=2, which is the highest power of a variable, but if a=0, the term x 2 is 0 and the equation becomes a linear equation. First, we enter the coefficient values of each term in the quadratic equation in the form of ax 2 + bx + c = 0 and store the values using ‘ a’, ’ b’ and ‘ c’ variables.Ģ.

*/ #include #include //Header file is include as we use sqrt function. The discriminant tells the nature of the roots. Quadratic Equation C++ Implementation Here, The term b2-4ac is known as the discriminant of a quadratic equation. In this program, you’ll learn to find Find Quadratic Equation Roots and All Roots of a Quadratic Equation. Then the program should calculate the solution considering the following circumstances. if a = 0 the equation becomes a first degree equation, that may or may not have solutions.* C Program to determine the roots of a quadratic equation and their nature. The Quadratic equation is the equation of the form as below: ax2 + bx +c 0 Where x represents unknown and a, b and c are coefficients, it’s roots is given by following the formula. Write a program that calculates the real solution of the quadratic equation ax²+bx+c0 Read in the values for the parameters a,b,c (type float).you should check the return value of scanf() to detect invalid input.But it is just as easy to compute the complex components yourself. you can use complex numbers if the compiler supports them by defining x1 and x2 as complex double x1, x2.If its less than zero, the roots are imaginary, or if its. sqrt() is a real function, -1 is outside its domain. Depending upon the nature of the discriminant, formula for finding roots is be given as. For a quadratic equation ax2+ bx + c 0 (a0), discriminant (b2-4ac) decides the nature of roots.
