Answer:


9x^4-11x^3+2x^2+36x-8

Explanations:

Given the product of the functions as shown below:


(9x-2)(x^3-x^2+4)

Expand the bracket using the distributive law


9x(x^3)-9x(x^2)+9x(4)-2(x^3)+2(x^2)-2(4)

Multiply out and collect the like terms;


\begin{gathered} 9x^4-9x^3+36x-2x^3+2x^2-8 \\ 9x^4-9x^3-2x^3+2x^2+36x-8 \end{gathered}

Take the sum of the like terms;


9x^4-11x^3+2x^2+36x-8

This gives the simplified form of the product
