If (2x + 2/x) = 1, Then The Value Of (x^3 + 1/x^3) Is?

Answer»

(2X + 2/X) = 1

=> (x + 1/x) = 1/2

(x^3+1/x^3) = (x+1/x)^3-3x*1/x(x+1/x)

= (1/2)^3-1/2 = (1/8 - 3/2) = (1-12)/8= -11/8.

(2x + 2/x) = 1

=> (x + 1/x) = 1/2

(x^3+1/x^3) = (x+1/x)^3-3x*1/x(x+1/x)

= (1/2)^3-1/2 = (1/8 - 3/2) = (1-12)/8= -11/8.
