Question

if x2 +1/2 =27 find the values of each of the following: (i) x+1/x (ii) x- 1/x

Answer 1

Answer:

$2x + \frac{1}{2} = 27 \\ 2x = 27 - \frac{1}{2} \\ 2x = \frac{54 - 1}{2 } \\ x = \frac{53}{2} \\ x = 26.5 \\ 1. = \frac{x + 1}{x} \\ = \frac{27.5}{26.5} \\ = \frac{55}{53} \\ 2. = \frac{x - 1}{x} \\ = \frac{25.5}{26.5} \\ = \frac{51}{53}$
