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!

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
