a=5
b=10
c=15

display

ax^2+10x=15

D=b^2-4ac

alpha=(-b+root(D)/2a


beta=(-b-root(D)/2a

put it is very ugly i want to display like math symbolic please give me any idea ,tutorial etc.... my code

You don't need any library, you can format the String as HTML and display it.

For example, if you want to display ax^2+10x=15 on the jbSolution button, you should do like this:

    int a=5, b=10, c=15;

    String j = "<html>"+a+"x<sup>2</sup>+"+b+" x = "+c+"</html>";
    jbSolution =new JButton(j);
    jbSolution.setBounds(20,150,130,30);

For D=b^2-4ac

String j = "<html>D = b<sup>2</sup> -  4ac</html>";

For beta=(-b-root(D)/2a

String j = "<html>beta=(-b-\u221AD)/2a</html>";

And how would you represent the square root in that ? – Damian Leszczyński - Vash Dec 12 '13 at 10:18
