Question

If F(z)=z^2 - 3 root 2z-1, then find the value of f(3 root 2)

Answer 1

f(3√2)=18-18-1=-1
is your answer

Answer 2

Answer

-1

Step-by-step explanation:

f(z)=z^2-3root2z-1

f(3root2)      =(3root2)^2-(3root2)(3root2)-1

                     =(3root2)-(3root2)-1

                     =-1
