Please solve if Possible pls take a pic thanks a lot for helping .

Answer 1

Step-by-step explanation:

Here

( 3 + 2√2)² + ( 3 - 2√2)²

according to formula ,

( 3)² + 2 .3 .2√2 + (2√2)² + 3² -(2.3.2√2) + (2√2)²

= 9 + 12√2 + 8 + 9 - 12√2 + 8

= 34 answers

Answer 2

Answer:

Step-by-step explanation:

[3 + $\sqrt[2]{2}$]² +[ 3 -$\sqrt[2]{2} ]^{2}$

3 ²+ $\sqrt[2]{2}$² + 3 ² - $\sqrt[2]{2} ^{2}$

= 9 + $2x^{\frac{1}{2}X 2 }$ + 9 - $2x^{\frac{1}{2}X 2 }$

= 18 + 2x - 2x

= 18
