Express $\frac{2}{x + 3} - \frac{1}{x - 2}$ as a simple fraction

A.

$\frac{x - 7}{x^2 + x - 6}$

B.

$\frac{x - 1}{x^2 + x - 6}$

C.

$\frac{x - 2}{x^2 + x - 6}$

D.

$\frac{x - 27}{x^2 + x - 6}$

View answer & explanation

Correct answer is A

$\frac{2}{x + 3} - \frac{1}{x - 2}$ = $\frac{2(x - 2) - (x - 3)}{(x + 3) (x - 2)}$

= $\frac{2x - 4 - x - 3}{x^2 - 2x + 3x - 6}$

= $\frac{x -7}{x^2 + x - 6}$

= $\frac{x - 7}{x^2 + x - 6}$
