How to solve step by step the following polynomial factoring problem: (x + 3) - x(x^{2} + 6x+9)

Step-by-step explanation:

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

happens to factor nicely into , and putting that into our expression gets us

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

Simplifying that expression on the right:

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

a. -0.3 > -0.33

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5
