Simplify \(\frac{2}{2 + x} + \frac{2}{2 – x}\)
- \(\frac{4}{4 - x^3}\)
-
\(\frac{8}{4 - x^2}\)
- \(\frac{4x}{4 - x^2}\)
- \(\frac{8 - 4x}{4 - x^2}\)
The correct answer is: B
Explanation
\(\frac{2}{2 + x} + \frac{2}{2 - x}\)\(\frac{2(2 - x) + 2(2 + x)}{(2 + x)(2 - x)} = \frac{4 - 2x + 4 + 2x}{4 - 2x + 2x - x^2}\)
= \(\frac{8}{4 - x62}\)
