You can put this solution on YOUR website!

The formula is:



But in order to know what , , and are, you have to put your equation into standard form. Standard form is:



Your equation is



Add -30 to both sides



So far, so good, but you don't have a first degree term. That means must be zero!



Now you can see that , , and

Just plug the numbers into the formula and do the arithmetic.
