(x^2-1)^-6(x^2-1)+9=?a^3-36a=?

(x^2-1)^-6(x^2-1)+9=?a^3-36a=?
(x^2-1)^-6(x^2-1)+9=?
a^3-36a=?

(x^2-1)^-6(x^2-1)+9=?a^3-36a=?
(x^2-1)^2-6(x^2-1)+9
=(x^2-1-3)^2
=(x^2-4)^2
=(x+2)^2(x-2)^2
a^3-36a
=a(a^2-36)
=a(a-6)(a+6)

（x²-1）²-6（x²-1）+9
=(x^2-1)^2-2*(x^2-1)^3+3^2
=[(x^2-1)-3]^2
=(x^2-2^2)^2
=(x+2)^2*(x-2)^2

(x^2-1)^2-6(x^2-1)+9
=(x^2-1-3)^2
=(x^2-4)^2
=(x+2)^2(x-2)^2
a^3-36a
=a(a^2-36)
=a(a-6)(a+6)

x^2-1)^2-6(x^2-1)+9
=(x^2-1-3)^2
=(x^2-4)^2
=(x+2)^2(x-2)^2
