x^6+3x^3+2=0

It can also be written as:

(x^3)^2+3(x^3)+2=0...........(1)

Let a=(x^3), then we may rewrite equation (1) as:

a^2+3a+2=0

or,a^2+a+2a+2=0

or,a(a+1)+2(a+1)=0

or,(a+1)(a+2)=0

either,a=-1 or,a=-2

that is (x^3)=-1 or (x^3)=-2

Therefore, x=-1 or x=cube root of -2

this is the solution to your equation.
