(a-b)^2=a^2+b^2-2ab
(a+b)^2=a^2+b^2+2ab
(2√2-5)^2=(2√2)^2+5^2-2(2√2)(5) =4×2+25-20√2
=33-20√2....(1)
(3√2+√3)^2=(3√2)^2+(√3)^2+2(3√2)√3
=9×2+3+6√6
21+6√6....(2)
(√2-1)^2= (√2)^2+1-2(√2)1
=2+1-2√2
3-2√2...(3)
add (1) and (2)
33-10√2+21+6√6=54-20√2+6√6..(4)
subtract (3) from (4)
54+6√6-20√2-3+2√2
=51+6√6-18√2
