If a - \(\frac{1}{a - 5}\) = 11 Then find , (a - 5)2 + \(\frac{1}{(a - 5)^2}\) |
40 38 42 36 |
38 |
Given = a - \(\frac{1}{a - 5}\) = 11 By subtracting 5 on both sides we get, (a - 5) - \(\frac{1}{a - 5}\) = 11 - 5 = 6 (a - 5)2 + \(\frac{1}{(a - 5)^2}\) = 62 + 2 = 38
If x - \(\frac{1}{x}\) = a then, (x)2 + \(\frac{1}{(x)^2}\) = a2 + 2 |
