Factor polynomial $$ x^{3}+x^{2}+3x $$

$$ x^{3}+x^{2}+3x = x( x^{2}+x+3 ) $$

Step 1 :

After factoring out $ x $ we have:

$$ x^{3}+x^{2}+3x = x ( x^{2}+x+3 ) $$

Step 2 :

Step 2: Identify constants $ \color{blue}{ b }$ and $\color{red}{ c }$. ( $ \color{blue}{ b }$ is a number in front of the $ x $ term and $ \color{red}{ c } $ is a constant). In our case:

$$ \color{blue}{ b = 1 } ~ \text{ and } ~ \color{red}{ c = 3 }$$

Now we must discover two numbers that sum up to $ \color{blue}{ 1 } $ and multiply to $ \color{red}{ 3 } $.

Step 3: Find out pairs of numbers with a product of $\color{red}{ c = 3 }$.

PRODUCT = 3
1     3	-1     -3

Step 4: Because none of these pairs will give us a sum of $ \color{blue}{ 1 }$, we conclude the polynomial cannot be factored.
