Int solution (double a, b double, double c, double & amp; X1, double & amp; X2)

Double d;
D=b * * a * b - 4 c.
If (if d> 0)
{
X1=(a - b + SQRT (d))/(2 * a);
X2=(a - b + SQRT (d))/(2 * a);
Return 2;

Else if (d==0)

The else
return 0;

Bosses, can't ah, give write full point

CodePudding user response:

Ask questions should be clear, the problem is very difficult for others to guess, you this function is avoids solving quadratic equation? A, b, c equation coefficient, x1, x2 used to receive the equation root,
