Answer:
The answer in B please mark Brainliest.
Step-by-step explanation:
It is very easy.
just use FOIL (First, Outer, Inner, Last).
( √2 - √3 ) X ( √2 - √3 )
First: √2 X √2 = 2
Outer: √2 X -√3 = -√6
Inner: -√3 X √2 = -√6
Last: -√3 X -√3 = 3
and then add them together.
2 - √6 - √6 + 3
5 - 2(√6)
The answer is 5 - 2(√6) .

Oh, I adore magic squares!
We need all rows to be equivalent, so try adding up the bottom (complete) row to get 7x-4x+3x=10x-4x=6x.
To solve the middle number, we have -2x+X+6x=6x, so X=2x.
To solve the top number, we have X+8x-3x=6x, so X=6x-8x+3x=x
Now check first column,
x-2x+7x=6x ok
Second column
8x+2x-4x=6x ok
Top-right to bottom-right diagonal: x+2x+3x=6x, ok
Bottom-left to top right diagonal: 7x+2x-3x=6x
So everything is ok!
