| ① | Multiply $6$ by $ \dfrac{x^2}{12x^4+24x^3} $ to get $ \dfrac{ 6x^2 }{ 12x^4+24x^3 } $. Step 1: Write $ 6 $ as a fraction by putting $ \color{red}{1} $ in the denominator. Step 2: Multiply numerators and denominators. Step 3: Simplify numerator and denominator. $$ \begin{aligned} 6 \cdot \frac{x^2}{12x^4+24x^3} & \xlongequal{\text{Step 1}} \frac{6}{\color{red}{1}} \cdot \frac{x^2}{12x^4+24x^3} \xlongequal{\text{Step 2}} \frac{ 6 \cdot x^2 }{ 1 \cdot \left( 12x^4+24x^3 \right) } = \\[1ex] & \xlongequal{\text{Step 3}} \frac{ 6x^2 }{ 12x^4+24x^3 } \end{aligned} $$ |
