(Root 3+ double root 2) squared equal to Square of bracket (root 3+ double root 2) equals? (Minus one in two minus three)?

(Root 3+ double root 2) squared equal to Square of bracket (root 3+ double root 2) equals? (Minus one in two minus three)?

(√3+2√2)^2
=(√3)^2+2*√3*2√2+(2√2)^2
=3+4√6+8
=11+4√6
[(-1-√3)/2]^2
=(1+√3)^2/4
=(1+2√3+3)/4
=(3+2√3)/4

Given that n is a positive integer, and the square of absolute value a-b+1 absolute value +(c+d+2009)=0, find the value of 2n-1th power of 2d (a-b)+(c-d)(a-b)2n-1th power Given that n is a positive integer, and the square of absolute value a-b+1 absolute value +(c+d+2009)=0, obtain the value of 2n-1 power of 2d (a-b)+(c-d)(a-b)2n-1 power

Absolute a-b+1 Square of absolute +(c+d+2009)=0
Note a-b=-1 and c+d=-2009
2N-1 power of 2d (a-b)+2n-1 power of (c-d)(a-b)
=-2D-(c-d)
=-C-d
=2009
