Question

(9x³-6x) (-2x²+4) pls help me and its polynomials

Answer 1

We want to expand the equation;

`(9x^3-6x)(-2x^2+4)`

We need to multiply each of the terms in the first bracket by each term in the second bracket.

`\begin{gathered} (9x^3-6x)(-2x^2+4) \\ 9x^3(-2x)+9x^3(+4)-6x(-2x^2)-6x(+4) \\ -18x^4+36x^3+12x^3-24x \\ -18x^4+48x^3-24x \end{gathered}`

Therefore, expanding the given equation gives;

`-18x^4+48x^3-24x`
