Answer:

(x + 3) - x(x² + 6x + 9)

= (x + 3) - x(x + 3)²

= (x + 3)[1 - x(x + 3)]

= (x + 3)(1 - x² - 3x)

Step-by-step explanation:

Answer:

[tex](x+3)(1-x^2-3x)[/tex]

Step-by-step explanation:

First, let's factor that quadratic on the right:

[tex]x^2+6x+9[/tex] happens to factor nicely into [tex](x+3)^2[/tex], and putting that into our expression gets us

[tex](x+3)-x(x+3)^2[/tex]

Factoring out an (x + 3) from each term, we get

[tex](x+3)[1-x(x+3)][/tex]

Simplifying that expression on the right:

[tex](x+3)(1-x^2-3x)[/tex]

We can't factor that right-side expression any more, so we can just leave it like that!
