Hello I am creating a program that solves the quadratic equation ax^2 + bx +c.

I have this program almost complete except the output of the equation in the function called display_quadratic. I need the program to display the variables a,b,c in the equation ax^2 + bx + c but I am having 2 problems. My first problem is that I cannot get the right addition and subtraction signs for the equation.

For instance, if the program had the values for a,b,c as 2,2,3

it will display 2x^2 2x 3

How can I get it to display 2x^2 + 2x + 3? or if it was negative like 2x^2 - 2x - 3?

My next question is how do I get to not display the coefficients that are 1?

I had an if-else statement but no matter what I created it would overlap with another statement and print out twice. Any help is appreciated and welcomed. Thank you.

Here is the code:

Code:`#include <stdio.h>`

#include <stdlib.h>

#include <math.h>

void display_quadratic (float a, float b, float c);

float root1(float a, float b, float c);

float root2(float a, float b, float c);

float discriminant (float a, float b, float c);

float r1,r2;

int

main (void)

{

float a,b,c;

printf("This program solves the quadratic equation ax^2 + bx + c == 0.\n");

printf("Enter a, b, and c:");

scanf("%g%g%g", &a, &b, &c);

printf("OK, the equation you're specifying is:");

display_quadratic(a,b,c);

printf(" == 0\n");

r1 = root1(a,b,c);

r2 = root2(a,b,c);

printf("The roots of your equation are %g and %g, and the factorization is:\n ", r1,r2);

display_quadratic(a,b,c);

printf(" == ");

if (r1 > 0)

{

printf("(x - %g)", r1);

}

else

printf("(x + %g)", (r1 * -1));

if (r2 > 0)

{

printf("(x - %g)", r2);

}

else

printf("(x + %g)", (r2 * -1));

}

void display_quadratic (float a, float b, float c)

{

if (a == 1){

printf("x^2 ");}

else printf("%gx^2 ", a);

if (b == 1){

printf("x ");}

else printf("%gx ", b);

printf("%g ", c);

}

float discriminant (float a, float b, float c)

{

return (pow(b,2) - 4 * a * c);

}

float root1 (float a, float b, float c)

{

float root1_calculator;

root1_calculator = (-b + sqrt(discriminant(a,b,c)))/2 * a;

return (root1_calculator);

}

float root2 (float a, float b, float c)

{

float root2_calculator;

root2_calculator =(-b - sqrt(discriminant(a,b,c)))/2 * a;

return (root2_calculator);

}
