To simplify the expression (x+5)/(x-3)*(7x^2 - 21x) / (7x), we can cancel out common factors.
First, we can cancel out the common factor of (x) in the numerator and denominator of the first fraction, resulting in (x+5)/(x-3).
Next, we can cancel out the common factor of (7x) in the numerator and denominator of the second fraction, resulting in (7x^2 - 21x) / 1.
Combining these simplified fractions, we get (x+5)/(x-3) * (7x^2 - 21x).
Therefore, the simplified expression is (x+5)(7x^2 - 21x) / (x-3).
