Since the denominator of a rational expression cannot be equal to zero ,  

To solve this equation we must write all terms with a common denominator and let the numerators become the equation:

Substitute a = 5, b = 6 and c = -22 into the quadratic formula and simplify:

The roots of the equation are

( Note: The radical in the formula must be simplified when solving equations: and the expression reduced as much as possible for stating the roots )
