Question

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

Answer 1

Answer:

2

Step-by-step explanation:

Hello

We can notice that

$2^3=2\times 2\times 2=8$

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

$x^3-8=(x-2)(x^2+2x+4)\\ \\ \Delta=2^2-4\times4=4-16=-12$

So there is no other real solution.

Thanks
