Answer:
[tex]2d^3-7d^2-103d+36[/tex]
Step-by-step explanation:
The given expressions are (d-9) and [tex]2d^2+11d-4[/tex].
Their product is given by:
[tex](d-9)(2d^2+11d-4)[/tex]
We expand using the distributive property to obtain;
[tex]d(2d^2+11d-4)-9(2d^2+11d-4)[/tex]
[tex]2d^3+11d^2-4d-18d^2-99d+36[/tex]
We group similar terms to get;
[tex]2d^3+11d^2-18d^2-4d-99d+36[/tex]
We combine the similar terms to get:
[tex]2d^3-7d^2-103d+36[/tex]
