This question is taken from quadratic equation chapter in which we have given a equation x²-1/x²=5 and we have to prove that the given equation is a quadratic equation
Kindly solve the above problem in detail
RS Aggarwal, Class 10, chapter 4A, question no 1(viii)
x²+1/x²=5
(x4+1)/x²=5
x4+1=5x²
x4−5x²+1=0
It is not of the form ax²+bx+c=0
Therefore,the given equation is not a quadratic equation.
