Answer:

x = 0

Step-by-step explanation:

[tex]x^3-7x^2-x =0\\[/tex]

Take out common factor

[tex]x(x^2-7x-1) = 0[/tex]

The factor inside the parenthesis cannot be factored

Since there is a common factor that we pulled out of the original equation,

set that x equal to zero and solve

[tex]x = 0\\[/tex] : Therefore x = 0
