Answer 2

Logical Method :

Steps :
1) To get the polynomial whose roots are Just inverse of the original one.
Replace x with 1/x .

Here, Original Equation.

${t}^{2} - t - 4 = 0$
Now, Replace t with 1/t .

We get,
(1/t)^2 -(1/t) -4=0
=> 1 - t -4t^2 =0
=> 4t^2+t -1 =0


Required Polynomial is
4t^2 +t - 1
