program for a quadratic formula

Math ...
Here's the link to the Math class and it's methods:

PS: I think you're looking for the sqrt() methodChris S.

What you need is the Java API. It will have all the info you need. Here's the API for the Math class:
Math (Java Platform SE 6)
And the "Master" API:

it much faster to use int sideA = a*a; then to use the Math class.

you could actually cal for sqrt, but its a crazy math formular. better to use Math.sqrt() for that part...USE CODE TAGS> [CODE]...[/CODE]

huh?
Angryboy... you on something? Let's see... I give a link to the Math class and tell the OP that the sqrt() is probably what is needed. How did you come to the conclusion that I was suggessting that the OP develop the sqrt() method? I think it would be obvious that I'm refering to the sqrt() method in the link to the Math class.
As for the a*a vs Math.pow(), yeah... that's sounds pretty logical...
