Write a C Program to Find all Roots of a Quadratic Equation. This program accepts coefficients of a quadratic equation from the user and displays the roots (both real and complex roots depending upon the discriminant ). The standard form of a quadratic equation is: ax2 + bx + c = 0, where a, b and c are real numbers and a ≠ 0 The term b 2 -4ac is known as the discriminant of a quadratic equation. The discriminant tells the nature of the roots. If discriminant is greater than 0, the roots are real and different. If discriminant is equal to 0, the roots are real and equal. If discriminant is less than 0, the roots are complex and different. Output Enter coefficients a, b and c: 2.3 4 5.6 Roots are: -0.87+1.30i and -0.87-1.30i In this program, library function sqrt() is used to find the square root of a number.
