Simplify; (frac{2}{1 – x} – frac{1}{x})
-
A.
(frac{x + 1}{x(1 – x)}) -
B.
(frac{3x – 1}{ x(1 – x)}) -
C.
(frac{3x + 1}{ x(1 – x)}) -
D.
(frac{x + 1}{ x(1 – x)})
Correct Answer: Option B
Explanation
(frac{2}{1 – x} – frac{1}{x}) = (frac{2x – 1(1 – x)}{x(1 – x)})
= (frac{2x – 1(1 + x)}{x(1 – x)})
= (frac{3x – 1}{x(1 – x)})
