If a - \(\frac{1}{a - 9}\) = 11 Then find , (a - 9)2 + \(\frac{1}{(a - 9)^2}\) |
6 10 121 119 |
6 |
Given = a - \(\frac{1}{a - 9}\) = 11 By subtracting 9 on both sides we get, (a - 9) - \(\frac{1}{a - 9}\) = 11 - 9 = 2 (a - 9)2 + \(\frac{1}{(a - 9)^2}\) = 22 + 2 = 6
If x - \(\frac{1}{x}\) = a then, (x)2 + \(\frac{1}{(x)^2}\) = a2 + 2 |
