Final Answer :
Steps:
1)
General Method :
If α and β are are zeroes of the quadratic polynomial x^2+2x+1 =0 .
Here,
αβ = 1
So,
α^2β = α * (αβ) = α * 1 = α
αβ^2 = (αβ)*β = β
2) Now, here we see that
Quadratic polynomial whose zeroes are α^2β and αβ^2 is same as quadratic polynomial whose zeroes are. α and β ,.
