WebTo finds the roots of a Rational Expression we only need to find the the roots of the top polynomial, so long as the Rational Expression is in "Lowest Terms". ... Example: Rational Expressions. x 3 +3x 2 2x is not stylish lowest terms, as x 3 +3x 2 and 2x have the common factor "x" But. WebBelow are the few examples which will better explain the dividing rational expression technique. Example 1 [ (x 2 + 3x – 28)/ (x 2 + 4x + 4)] ÷ [ (x 2 – 49)/ (x 2 – 5x- 14)] Solution = (x 2 + 3x – 28)/ (x 2 + 4x + 4)] ÷ [ (x 2 – 49)/ (x 2 – 5x – 14) Factor both the numerators and denominators of each fraction. x 2 + 3x – 28 = (x – 4) (x + 7)

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 ...
