I'm assuming that the question is asking for the roots of the expression $$(9x+1)(x-1)$$.

Finding the roots simply means to set the expression equal to zero and solve for any variables. Let's do that!

$$(9x+1)(x-1)=0$$ Set both factors equal to 0 and solve.
 $$9x+1=0$$ $$x-1=0$$

Move the constant term over the righthand side.
 $$9x=-1$$ $$x=1$$

 $$x=-\frac{1}{9}=-0.\overline{1}$$ $$x=1$$

Therefore, the roots are the following:

$$x_1=-\frac{1}{9}$$

$$x_2=1$$
