Question

resolve into factors:- x^6-36x^3-1

Answer 1

heya!!!.....here we have to consider x^3 as y......
so the new equation. ....
y^2-36y-1=0......so now by middle term splitting we have :......
the result

Answer 2

Answer

x^6-36x^3-1

=(x^2)^3+(-3x)^3+(-1)^3-3x^2(-3x)(-1)

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