=ω, cube root of unity ∴(1−x 2 +x) 6 −(1−x+x 2 ) 6
=(1−ω 2 +ω) 6 −(1−ω+ω 2 ) 6
=(−2ω 2 ) 6 −(−ω−ω) 6 , since 1+ω+ω 2 =0 =2 6 ω −2 6 ω 6
=2 6 −2 6 =0, since ω 3 =1 WHAT WAYS HARDWOOD TREES ARE USEFUL?IN WHAT WAYS HARDWOOD TREES ARE USEFUL?IN WHAT WAYS HARDWOOD TREES ARE USEFUL?IN WHAT WAYS HARDWOOD TREES ARE USEFUL?IN WHAT WAYS HARDWOOD TREES ARE USEFUL?IN WHAT WAYS HARDWOOD TREES ARE USEFUL?IN WHAT WAYS HARDWOOD THREES ARE USEFUL?
