It seems that $ x^{2}-25x+1250 $ 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:
$$ \color{blue}{ b = -25 } ~ \text{ and } ~ \color{red}{ c = 1250 }$$Now we must discover two numbers that sum up to $ \color{blue}{ -25 } $ and multiply to $ \color{red}{ 1250 } $.
Step 2: Find out pairs of numbers with a product of $\color{red}{ c = 1250 }$.
PRODUCT = 1250 | |
1 1250 | -1 -1250 |
2 625 | -2 -625 |
5 250 | -5 -250 |
10 125 | -10 -125 |
25 50 | -25 -50 |
Step 3: Because none of these pairs will give us a sum of $ \color{blue}{ -25 }$, we conclude the polynomial cannot be factored.
