Question

if x=3-√13÷2 what is the value of x^2 -1÷x^2​

Answer 1

Answer:

Explanation:

$( \frac{1}{x} + 2) + ( \frac{2}{x} - 1) = \frac{6}{x} \\ \\ \frac{1}{x} + 2 + \frac{2}{x} - 1 = \frac{6}{x} \\ \\ \frac{3}{x} + 1 = \frac{6}{x} \\ \\ \frac{6}{x} - \frac{3}{x} = 1 \\ \\ \frac{6 - 3}{x} = 1 \\ \\ \frac{3}{x} = 1 \\ \\ x = 3$
