Final answer:
To factor the expression 8x^3 - 3x completely, we can factor out the common factor x.
Step-by-step explanation:
To factor the expression completely, we first look for common factors between the terms. In this case, the common factor is x. We can factor it out as follows:
8x^3 - 3x = x(8x^2 - 3)
Now, we can see that the expression is completely factored.
