Error in Mathbook > Quadratic Equation

Originally reported on Google Code with ID 228 ``` x1 = (-b + sqrt(b^2 - 4*a*c)) / 2*a x1 = (-b - sqrt(b^2 - 4*a*c)) / 2*a

these two formulas are false; the term under the fraction bar must be in brackets:

x1 = (-b + sqrt(b^2 - 4*a*c)) / ( 2*a ) x1 = (-b - sqrt(b^2 - 4*a*c)) / ( 2*a )

otherwise the result is false... ```
