Question

When factored completely, 23 – 92 is equivalent to:O x(x-3)O x(x+3)(x-3)O (x-3)(x+3)O x(x+3)

Answer 1

`x^3-9x=x(x-3)(x+3)\rightarrow\text{ Option two}`

Step-by-step explanation: We need to factor out the given completly, it can be done as follows:

`Given\rightarrow x^3-9x`

Factoring completley give us:

`\begin{gathered} x^3-9x=x(x^2-9)=x(x^2-3^2)=x(x-3)(x+3) \\ \therefore\rightarrow \\ x^3-9x=x(x-3)(x+3)\rightarrow\text{ Option two} \end{gathered}`

The answer, therefore, is Option two:
