Given:

There are given the equation:

[tex]-x^3+22x^2-121x=0[/tex]

Explanation:

According to the question:

We need to find the value of x by using the factoring:

S0,

From the equation:

[tex]-x^{3}+22x^{2}-121x=0[/tex]

Tthen,

[tex]\begin{gathered} -x^{3}+22x^{2}-121x=0 \\ -x(x^2-22x+121)=0 \end{gathered}[/tex]

Then,

[tex]\begin{gathered} -x(x^2-22x+121)=0 \\ x(x-11)^2=0 \\ x=0; \\ x-11=0 \\ x=11 \end{gathered}[/tex]

Final answer:

Hence, the value of x by using factor method is shown below:

[tex]x=0,11[/tex]
