Given:

There are given the equation:

[tex]90x^3-20x[/tex]

Explanation:

To find the factor of the given equation, first, we need to take a common variable from the given equation:

[tex]90x^3-20x=x(90x^2-20)[/tex]

Then,

[tex]\begin{gathered} 90x^3-20x=x(90x^2-20) \\ =10x(9x^2-2) \end{gathered}[/tex]

Final answer:

Hence, the factor of the given equation is shown below:

[tex]\begin{equation*} 10x(9x^2-2) \end{equation*}[/tex]
