〈 x^{8 }_{-} 8x^{8}〉^{-2}

Tutors, please sign in to answer this question.

X^8 - 8 X^ ( 8 -2) =

Go to the Comment Section:

X^8 - X^6 =

X^6 ( X^2 - 1 ) = X ^6 ( X +1) ( X - 1)

x^{8} - **8**x^{(8-2)} = x^{8} - x^{6}

You kinda dropped an 8 out of there.

You are right thank you:

Correction willbe

X ^8 - 8 X^6 = X^6 ( X^2 - 8 ) = X^6 ( X + 2 √2) ( X - 2 √2)
