Factor polynomial $$ 8x^{2}+22x+2 $$

$$ 8x^{2}+22x+2 = 2( 4x^{2}+11x+1 ) $$

Step 1 :

After factoring out $ 2 $ we have:

$$ 8x^{2}+22x+2 = 2 ( 4x^{2}+11x+1 ) $$

Step 2 :

Step 2: 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:

$$ a = 4 , b = 11 ~ \text{ and } ~ c = 1 $$

Step 3: Multiply the leading coefficient $\color{blue}{ a = 4 }$ by the constant term $\color{blue}{c = 1} $.

$$ a \cdot c = 4 $$

Step 4: Find out two numbers that multiply to $ a \cdot c = 4 $ and add to $ b = 11 $.

Step 5: All pairs of numbers with a product of $ 4 $ are:

PRODUCT = 4
1     4	-1     -4
2     2	-2     -2

Step 6: Find out which factor pair sums up to $\color{blue}{ b = 11 }$

Step 7: Because none of these pairs will give us a sum of $ \color{blue}{ 11 }$, we conclude the polynomial cannot be factored.
