Question

If (x − 1/ x ) = 2, find the values of:
a) x + 1/x
b) x^2+1/x^2
c) x^ 4 + 1/x^4

Answer 1

Answer:

a) 0

b) 2

c)  2

Step-by-step explanation:

(x - 1)/x = 2

x - 1 = 2x

2x - x = -1

x = -1

a) (x +1)/x

put x = -1

 (-1 +1)/1

= 0/1

= 0

b) (x² + 1)/x²

put x = -1

[(-1)² + 1]/(-1)²

= (1 + 1)/1

= 2

c) (x⁴ + 1)/x⁴

put x = -1

[(-1)⁴ + 1)]/(-1)⁴

= (1 + 1)/1

= 2
