To divide the given rational expressions, we multiply the first expression by the reciprocal of the second expression. Given:
\frac {6x-12}{21x-14}\div \frac {2x-4}{3x-2}
Step 1: Find the reciprocal of the second fraction.Reciprocal of
is
.Step 2: Multiply the first fraction by the reciprocal of the second fraction.
\frac {6x-12}{21x-14} \times \frac {3x-2}{2x-4}
Step 3: Simplify the expression.
\frac {(6x-12)(3x-2)}{(21x-14)(2x-4)}
Step 4: Factor out common terms in the numerator and denominator.
\frac {6(3x-2)}{21(2x-4)}
Step 5: Simplify further.
\frac {18x-12}{42x-28}
Step 6: Simplify the fraction.
\frac {18x-12}{42x-28} = \frac {3(6x-2)}{7(6x-2)}
Step 7: Cancel out common terms.
\frac {3}{7}
Therefore, the simplified expression is
.
