Question

Solve for all solutions of the equation. Show all work for full credit. X^3-8=0

Answer 1

2

Explanation:

Hello

We can notice that

`2^3=2* 2* 2=8`

so 2 is one solution, we can put (x-2) in factor

`x^3-8=(x-2)(x^2+2x+4)\\ \\ \Delta=2^2-4*4=4-16=-12`

So there is no other real solution.

Thanks
