@ Arun you are right. can you please state an exmple. i thought of f(x)=x^2 and g(x)=x^2. but this is not satisfying the condition.

Let xo be a. real root of f(x)

then you have f(x₀² + 1) = f(x₀) g(x₀) = 0

that is xo² +1 is a root of f(x) as well

since h(x) = x² + 1 > x for x belongs to R,it is clear that any h^k (x₀) is rpeal root of f(x), even with k> m

But f(x) has a maximum of m roots. Hence contradiction, f(x) has no realroot

Given that (1+5x)⁴ = 1 + Px + Qx² + Rx³ +..... Find the values of P - 2Q + 3R
