Answer:
x³ - 3x² - 18x

Explanation:
Before we begin, remember the following:
xᵃ * xᵇ = xᵃ⁺ᵇ

Now, for the given:
To solve thus question, we will simply multiply each term from the first bracket by each term from the second bracket and then combine like terms to get the final answer.

This can be done as follows:
(x + 3)(x² - 6x)
x(x²) + x(-6x) + 3(x²) + 3(-6x)
x³ - 6x² + 3x² - 18x
x³ - 3x² - 18x

Hope this helps :)

Hey there :)

( x + 3 )( x² - 6x )

Now, we know what the FOIL method is:
First terms Outer terms Inner terms Last terms
We multiply as the method's full form clearly states

( x )( x² ) + x ( - 6x ) + 3 ( x² ) + 3 ( - 6x )
     ↓               ↓               ↓             ↓
  First         Outer       Inner        Last

x³ - 6x² + 3x² - 18x

Combine any like terms
x³ - 3x² - 18x

Your answer will be [tex]\boxed {Option \ A }[/tex]
