It seems that $ 4x^{2}+3x+11 $ 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 $\color{blue}{ a = 4 }$ by the constant term $\color{blue}{c = 11} $.
$$ a \cdot c = 44 $$Step 3: Find out two numbers that multiply to $ a \cdot c = 44 $ and add to $ b = 3 $.
Step 4: All pairs of numbers with a product of $ 44 $ are:
PRODUCT = 44 | |
1 44 | -1 -44 |
2 22 | -2 -22 |
4 11 | -4 -11 |
Step 5: Find out which factor pair sums up to $\color{blue}{ b = 3 }$
Step 6: Because none of these pairs will give us a sum of $ \color{blue}{ 3 }$, we conclude the polynomial cannot be factored.
