Explanation
| $$ \begin{aligned}\frac{x^2+x-2}{3x^2-4x+1}& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}\frac{x+2}{3x-1}\end{aligned} $$ | |
| ① | Simplify $ \dfrac{x^2+x-2}{3x^2-4x+1} $ to $ \dfrac{x+2}{3x-1} $. Factor both the denominator and the numerator, then cancel the common factor. $\color{blue}{x-1}$. $$ \begin{aligned} \frac{x^2+x-2}{3x^2-4x+1} & =\frac{ \left( x+2 \right) \cdot \color{blue}{ \left( x-1 \right) }}{ \left( 3x-1 \right) \cdot \color{blue}{ \left( x-1 \right) }} = \\[1ex] &= \frac{x+2}{3x-1} \end{aligned} $$ |
