Explanation
| $$ \begin{aligned}sqrt\frac{4x+4}{2}& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}\frac{4qrstx+4qrst}{2}\end{aligned} $$ | |
| ① | Multiply $qrst$ by $ \dfrac{4x+4}{2} $ to get $ \dfrac{ 4qrstx+4qrst }{ 2 } $. Step 1: Write $ qrst $ as a fraction by putting $ \color{red}{1} $ in the denominator. Step 2: Multiply numerators and denominators. Step 3: Simplify numerator and denominator. $$ \begin{aligned} qrst \cdot \frac{4x+4}{2} & \xlongequal{\text{Step 1}} \frac{qrst}{\color{red}{1}} \cdot \frac{4x+4}{2} \xlongequal{\text{Step 2}} \frac{ qrst \cdot \left( 4x+4 \right) }{ 1 \cdot 2 } = \\[1ex] & \xlongequal{\text{Step 3}} \frac{ 4qrstx+4qrst }{ 2 } \end{aligned} $$ |
