Sep 26, 2018  A quadratic equation is in the form ax 2 + bx + c. The roots of the quadratic equation are given by the following formula − There are three cases − b 2 4.a.c - The roots are real and both roots are different. The program to find the roots of a quadratic equation. Feb 13, 2011  Write a C program that solves quadratic equation to find its roots. The roots of a quadratic equation ax2+bx+c=0 (where a is not zero) is given by the formula: x=(-b±√(b^2-4ac))/2a Note:To find the square root of a number, use the function sqrt and include the math library. Where (b^2-4ac) is the discriminant.

I am supposed to write a program that asks for the coefficients a, b, and c of a quadratic equation ax2+bx+c=0. It needs to display to the screen one of the following:
• two distinct real numbers (when b2-4ac > 0),
• two distinct complex numbers (when b2-4ac < 0), or
• one real number (when b2-4ac = 0)

In case anyone reading this doesn't know, quadratic equation is: x = (-b +- sqrt((b^2)-4ac))/2a Now my question is, how would I put that into C in my program? (I haven't started it yet because I want to figure out how to write this equation into it first) Thanks! Implement the function findRoots to find the roots of the quadratic equation: ax 2 + bx + c = 0. The roots of the quadratic equation can be found with the following formula: For example, the roots of the equation 2x 2 + 10x + 8 = 0 are -1 and -4.

If I change the last statement to 'if else' the program works, but I don't think that would be correct. Please help.

It's a syntax error as written, and won't compile, so it can't be run. Why would you think this is more correct?

You're also not declaring a, b, and c. Please post actual code and wrap it in code tags.

It would be less redundant to use a temporary, say

Dev C++ Quadratic Equations

instead of recalculating it several times. It is also cleaner, clearer, and easier to read.
