Question

2 + i is a root of x2 + ax+b=0
where a,b are real then (a,b)=​

Answer 1

Step-by-step explanation:

we have to put the values and we will get the answer of the equation

pls mark it as brillant

I will not be able to give the solution as my classes are going on

Answer 2

P(X)=x

2

+ax+b a,b∈R

Roots are real

g(x)=p(x

3

)4

x

3

=t

g(x)=p(t)

p(t)=t

2

+at+b

Roots are real but t=x

3

Let t=β

x

3

=β

x=(β)

),w

2

Only 1 real root, 2−image.

Same are other roots

t=γ

It has only one real root

Total 2− distinct real roots and 4− Image.

hope it helps you
