Question

What is the product of d – 9 and 2d2 + 11d – 4?

Answer 1

The answer to your question is 2d^3-7d^2-103d+36

Answer 2

`2d^3-7d^2-103d+36`

Explanation:

The given expressions are (d-9) and
`2d^2+11d-4`.

Their product is given by:

`(d-9)(2d^2+11d-4)`

We expand using the distributive property to obtain;

`d(2d^2+11d-4)-9(2d^2+11d-4)`

`2d^3+11d^2-4d-18d^2-99d+36`

We group similar terms to get;

`2d^3+11d^2-18d^2-4d-99d+36`

We combine the similar terms to get:

`2d^3-7d^2-103d+36`
