Question

(X-1/ X + 1)^4 - 13 (X-1/ X + 1)^2 - 36=0

Answer 1

let (x-1/x+1)² be y

then the equation comes to be

y²-13y-36 = 0

y = 13±√169+144/2

= 13±√313/2

13+√313/2 = (x-1/x+1)²

by solving the equation

you will get the answer

Answer 2

Answer:

Step-by-step explanation:

actually in the previous answer the main formula involved is shreedaracharya formula.

∞=-b±√b∧2-4ac/2a.

where ∞ is the one of the two roots of the equation ax∧2+bx+c=0

and the roots of the equation ax∧2+bx+c=0
