The following rational equation has denominators that contain variables. For this equation, 1. Write the value or values of the variable that make a denominator zero. These are the restrictions on the variable. 2. Keeping the restrictions in mind, solve the equation. 2x =4 – _8_ x+4 x+4 The denominator is 0 when x+4=0 => x=-4 So when x = -4 the denominator will be 0 4 8 2 8 2 4 8 16 4 2 ) 4 ( | 4 8 16 4 4 2 4 8 4 4 2 ) 4 - = - = - = - - + = + + - + = + + - = + + x x x x x x x x x x x x x x x Solve the radical equation.

The solution set is x1 and x2 but they are not in the range of the REAL numbers.
