Answer 1

Step-by-step explanation:

Hey mate!

_______________________

Given :

x = 3 - 2x=3−2 2

To find :

x 2 + x 21

Solution :

x=3−2 2

x1= 3−2 2

1 × 3+2 23+2 2

x1 = (3) 2 −(2 2 ) 23+2 2

x1 = 9−83+2 2

x1 =3+22

Now,

x+ x1

=3− 2 2 +3+ 22

x+ x1 =3+3

x+ x1 =6

Again,

(x+ x1 )

2 =(6) 2

x 2+ x 2

1 +2× x× x 1 =36

x 2 + x 21

+2=36

x 2 + x 21

=36−2

∴

x 2+ x 2 1

=34
