pls help with my school project... its a program that get the factors of an algebriac expression... my problem is the output... when i input a = 1, b = 5, c =6 the output is correct but when i input a = 5, b = 26, c = 24 the output is (4x+6)(1x+5) the correct output must be (5x+6)(1x+4)..

here's my wrong work.. pls help me correct it.. i've been working it for 2 weeks and i still can't make it right..

Code:
```#include<stdio.h>
void factor(int a,int b,int c);
void factor1(int a,int b,int c,int d);

main()
{
int a,b,c;
clrscr();
printf("enter the value of a,b,c for the equation ax^2 + bx + c:\n");
printf("a = ");
scanf("%d",&a);
printf("b = ");
scanf("%d",&b);
printf("c = ");
scanf("%d",&c);
printf("the equation now is %dx^2 + %dx + %d",a,b,c);
factor(a,b,c);
getch();
}

void factor(int a,int b, int c)
{
float sum;
int i=0,start,fctr1;
start = a * c;
do
{
i++;
if(start%i==0){
fctr1=start/i;
sum=fctr1+i;}
}while(sum>b);
if(sum==b){
printf("\nThe equation is factorable and\nthe factors are: ");
factor1(fctr1,a,c,i);}
else
printf("\nThe equation is not factorable!!");
}

void factor1(int a,int b,int c,int d)
{
float w,y,l,i,n,e;
int x=0,z=0;
do
{
do
{
x++;
w=a/x;
n=w*x;
}while(n<a);
do
{
z++;
y=d/z;
e=y*z;
}while(e<d);
l=x*z;
i=y*w;
}while((l<c)&&(i>b));
if((w==y)&&(z==x))
printf("(%.0fx+%i)^2",w,z);
else
printf("(%.0fx+%i)(%.0fx+%i)",w,z,y,x);
}```
