Question

(2√2-3√3)^2+2(√3+3√2)^2-12*(5√2+1)(5√2-1)=

Answer 1

8-12√6-27+(2√3+6√2)^2-12×(50-1)= -19-12√6+12+24√6+72-12×49=65+12√6-588= -523+12√6

Answer 2

(2√2-3√3)^2+2(√3+3√2)^2-12*(5√2+1)(5√2-1)=8-12√6 +27+2(3+6√6+18)-12×(25×2-1)= 8-12√6 +27+2(21+6√6)-12(50-1)= 8-12√6 +27+42+12√6-12×49= 8+27+42-588= -511
