Step 1 :
After factoring out $ 4 $ we have:
$$ 44p^{2}+52p+8 = 4 ( 11p^{2}+13p+2 ) $$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:
Step 3: Multiply the leading coefficient $\color{blue}{ a = 11 }$ by the constant term $\color{blue}{c = 2} $.
$$ a \cdot c = 22 $$Step 4: Find out two numbers that multiply to $ a \cdot c = 22 $ and add to $ b = 13 $.
Step 5: All pairs of numbers with a product of $ 22 $ are:
| PRODUCT = 22 | |
| 1 22 | -1 -22 |
| 2 11 | -2 -11 |
Step 6: Find out which factor pair sums up to $\color{blue}{ b = 13 }$
| PRODUCT = 22 and SUM = 13 | |
| 1 22 | -1 -22 |
| 2 11 | -2 -11 |
Step 7: Replace middle term $ 13 x $ with $ 11x+2x $:
$$ 11x^{2}+13x+2 = 11x^{2}+11x+2x+2 $$Step 8: Apply factoring by grouping. Factor $ 11x $ out of the first two terms and $ 2 $ out of the last two terms.
$$ 11x^{2}+11x+2x+2 = 11x\left(x+1\right) + 2\left(x+1\right) = \left(11x+2\right) \left(x+1\right) $$
