Find the Roots (Zeros) (x+1)x

If any individual factor on the left side of the equation is equal to ${\displaystyle 0}$, the entire expression will be equal to ${\displaystyle 0}$.

Set ${\displaystyle x+1}$ equal to ${\displaystyle 0}$ and solve for ${\displaystyle x}$.

Set ${\displaystyle x}$ equal to ${\displaystyle 0}$.

The final solution is all the values that make ${\displaystyle (x+1)x=0}$ true.
