**Quadratic equation without numbers??**

How would one go about solving an equation such as B

^{2}X

^{2}+2ABCX-ABC

^{2}for the value of x that equals zero?

All of the letters are constants except for X, so would this be a quadratic equation problem.?

The solution in the book is somehow

x=(AC/B){[tex]\sqrt{1+(B/A)}[/tex])-1}

that -1 on the end is not the the negative 1 power, but -1
