Answer

The quotient is 3.

Solution

Calculate or simplify the expression \( (2x^2-12x)/(x^2-7x+6) \div (2x/(3x-3)) \). Simplify the expression by following steps: - step0: Solution: \(\frac{\left(2x^{2}-12x\right)}{\left(x^{2}-7x+6\right)}\div \left(\frac{2x}{\left(3x-3\right)}\right)\) - step1: Remove the parentheses: \(\frac{2x^{2}-12x}{x^{2}-7x+6}\div \left(\frac{2x}{3x-3}\right)\) - step2: Remove the parentheses: \(\frac{2x^{2}-12x}{x^{2}-7x+6}\div \frac{2x}{3x-3}\) - step3: Divide the terms: \(\frac{2x}{x-1}\div \frac{2x}{3x-3}\) - step4: Multiply by the reciprocal: \(\frac{2x}{x-1}\times \frac{3x-3}{2x}\) - step5: Reduce the fraction: \(\frac{1}{x-1}\times \left(3x-3\right)\) - step6: Rewrite the expression: \(\frac{1}{x-1}\times 3\left(x-1\right)\) - step7: Reduce the fraction: \(1\times 3\) - step8: Multiply the terms: \(3\) The quotient of the given expression is \(3\).

The Deep Dive

To solve the expression \(\frac{2 x^{2}-12 x}{x^{2}-7 x+6} \div \frac{2 x}{3 x-3}\), we will first convert the division into multiplication by taking the reciprocal of the second fraction. 1. **Rewrite the expression**: \[ \frac{2 x^{2}-12 x}{x^{2}-7 x+6} \div \frac{2 x}{3 x-3} = \frac{2 x^{2}-12 x}{x^{2}-7 x+6} \cdot \frac{3 x-3}{2 x} \] 2. **Factor the polynomials**: - For the numerator of the first fraction \(2 x^{2}-12 x\): \[ 2 x(x - 6) \] - For the denominator of the first fraction \(x^{2}-7 x+6\): \[ (x - 1)(x - 6) \] - For the numerator of the second fraction \(3 x - 3\): \[ 3(x - 1) \] - The denominator of the second fraction \(2 x\) is already in simplest form. 3. **Substituting the factored forms**: \[ \frac{2 x(x - 6)}{(x - 1)(x - 6)} \cdot \frac{3(x - 1)}{2x} \] 4. **Canceling common factors**: - The \(2x\) in the numerator and denominator cancels. - The \(x - 6\) in the numerator and denominator cancels. - The \(x - 1\) in the numerator and denominator cancels. After canceling we have: \[ \frac{3}{1} = 3 \] Thus, the quotient is \(\boxed{3}\).
