What is the LCD of the following rational expressions?

Aloiza [94]

$\dfrac{x}{x+1} \ , \ \dfrac{7x}{x-1}$

$\dfrac{x (x -1)}{(x+1)(x -1)} \ , \ \dfrac{7x(x+1)}{(x-1)(x+ 1)}$

<u>We know that (a + b)(a - b) = a² - b²:</u>

$\dfrac{x (x -1)}{x^2 - 1}} \ , \ \dfrac{7x(x+1)} {x^2 - 1}$

Answer: LCD = ( x + 1) (x - 1)
