QuestionMultiply the numerator and denominator of $$\frac{\frac{x}{x-2}-\frac{1}{x+1}}{\frac{2 x}{x-2}}$$ by which expression to simplify?

Studdy Solution
Now, we multiply the numerator and the denominator of the complex fraction by the LCD, $(x-2)(x+1)$.
$$\frac{\frac{x}{x-2}-\frac{1}{x+1}}{\frac{2 x}{x-2}} \times \frac{(x-2)(x+1)}{(x-2)(x+1)}$$This is the expression we would multiply into the numerator and denominator of the expression to simplify it.
