It seems that $ s^{2}+2s+50 $ cannot be factored out.
Step 1: 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:
$$ \color{blue}{ b = 2 } ~ \text{ and } ~ \color{red}{ c = 50 }$$Now we must discover two numbers that sum up to $ \color{blue}{ 2 } $ and multiply to $ \color{red}{ 50 } $.
Step 2: Find out pairs of numbers with a product of $\color{red}{ c = 50 }$.
PRODUCT = 50 | |
1 50 | -1 -50 |
2 25 | -2 -25 |
5 10 | -5 -10 |
Step 3: Because none of these pairs will give us a sum of $ \color{blue}{ 2 }$, we conclude the polynomial cannot be factored.
