title: how to put in mathematical equation in C
body: <p>I've been trying to look up on Google how to put in an equation in my program but wasn't able to find any. How do you include:</p>
  
  <pre><code>x = ( -b + √b2 - 4ac ) / 2a  
  </code></pre>
  
  <p>in the program?</p>
  
  <p>Here's my code:</p>
  
  <pre><code>{
      int a, b, c;
      float x;
  
      //statements
      printf("Enter three integers: ");
      scanf("%d %d %d", &amp;a, &amp;b, &amp;c);
  
      //computeforX
  
      x = ( -b + √b2 - 4ac ) / 2a  
  
      printf("The value of x is %.1f", x);
  
      return 0;
  }
  </code></pre>
