Example 2: Solve the rational equation below and make sure you check your answers for extraneous values. The first step in solving a rational equation is always to find the “silver bullet” known as LCD. So for this problem, finding the LCD is ... WebFor example, x != -2 in the rational expression: because replacing x with -2 makes the denominator equal 0. Similarly, in . x!=-2 and x!= -4 . The restrictions on the variable are found by determining the values that make the denominator equal to zero. In the second example above, finding the values of x that make (x + 2)(x + 4) = 0 requires ...
