Complex Rational Expression
These are the steps to solve for this problem.
1. You can write the expression as


%28%2825x%5E2-y%5E2%29%2F%289x%5E2z-4z%29%29 ÷ %28%285x-y%29%2F%283xz-2z%29%29+



2. Factor.
%28%285x-y%29%285x%2By%29%29%2F%28%28z%29%283x-2%29%283x%2B2%29%29 ÷ %28%285x-y%29%2Fz%283x-2%29%29+



3. Apply Division of Rational Expression
*If P%2FQ and R%2FS are rational expressions and Q ≠ 0, R ≠ 0 and S ≠ 0, then P%2FQ ÷ R%2FS = P%2FQ · S%2FR


%28%285x-y%29%285x%2By%29%29%2F%28%28z%29%283x-2%29%283x%2B2%29%29 · %28%28z%283x-2%29%29%2F%285x-y%29%29



4. Divide by Common Factor
