Question

Multiple polynomial and monomial 9r^3(r^2 - 3r +5)

Answer 1

Let's determine the product of the following equation:

`\text{ 9r}^3(r^2\text{ - 3r + 5)}`

We get,

`\text{ 9r}^3(r^2\text{ - 3r + 5)}`
`\text{ 9r}^3(r^2)+\text{ 9r}^3(\text{-3r) }+\text{ 9r}^3(\text{5)}`
`\text{ 9r}^{3\text{ + 2}}+(9)(-3)r^{3\text{ + 1}}+(9)(5)r^3`
`\text{ 9r}^5+(-27)r^4+(45)r^3`
`\text{ 9r}^5-27r^4+45r^3`

Therefore, the answer is:

`\text{ 9r}^5-27r^4+45r^3`
