No of real solution of equation (15+4*14^0.5)^t +(15-4*14^0.5)^t = 30 where t= x^2 – 2*|x| is …..

Question

Vikas TU · Answer

Dear Student,

let (15+4*14^0.5)^t = a

Then the given equation is a + 1/a = 30

Solving for a and then t we get t=1

X^2 – 2|x| = 1

|x|= 1+√5
X = -1-√5 , 1+√5

2 solutions

Cheers!!
