It seems that $ 5x^{2}+14x+14 $ cannot be factored out.
Step 1: Identify constants $ a $ , $ b $ and $ c $.
$ a $ is a number in front of the $ x^2 $ term $ b $ is a number in front of the $ x $ term and $ c $ is a constant. In this case:
Step 2: Multiply the leading coefficient $\color{blue}{ a = 5 }$ by the constant term $\color{blue}{c = 14} $.
$$ a \cdot c = 70 $$Step 3: Find out two numbers that multiply to $ a \cdot c = 70 $ and add to $ b = 14 $.
Step 4: All pairs of numbers with a product of $ 70 $ are:
PRODUCT = 70 | |
1 70 | -1 -70 |
2 35 | -2 -35 |
5 14 | -5 -14 |
7 10 | -7 -10 |
Step 5: Find out which factor pair sums up to $\color{blue}{ b = 14 }$
Step 6: Because none of these pairs will give us a sum of $ \color{blue}{ 14 }$, we conclude the polynomial cannot be factored.
