Question

[( 1/3-2√2 ) X ( 1/3+2√2^2 )] + [( 1/3-√2^2 ) X ( 1/3+2√2 )]

Answer 1

Answer:

8/9-12√2

Step-by-step explanation:

[( 1/3-2√2 ) X ( 1/3+2√2^2 )] + [( 1/3-√2^2 ) X ( 1/3+2√2 )]

simplify

[( 1/3-2√2 )x(1/3+2x2)}+{(1/3-2)x(1/3+2√2)}

multiply

[( 1/3-2√2 )x(1/3+4)}+(-5/3x(1/3+2√2)}

remove the parenthesis

{(1/3-2√2)x13/3)+(-5/9-10√2/3)

remove the parenthesis

(13/9-26√2/3)-5/9-10√2/3

subtract calculate

(13/9-26√2/3)-5/9-10√2/3

answer

8/9-12√2
