Formula used:
The factors of a polynomial can be find by taking a common factor and this method is called factor by grouping,
$ab+ac+bd+cd=a\left(b+c\right)+d\left(b+c\right)$
$=\left(a+d\right)\left(b+c\right)$
Or,
$ab-ac+bd-cd=a\left(b-c\right)+d\left(b-c\right)$
$=\left(a+d\right)\left(b-c\right)$
Calculation:
Consider the polynomial $2{x}^{3}+6{x}^{2}+x+3$.
This is a four term polynomial, factorization of this polynomial can be find by factor by grouping as,
$2{x}^{3}+6{x}^{2}+x+3=\left(2{x}^{3}+6{x}^{2}\right)+\left(x+3\right)$
$=2{x}^{2}\left(x+3\right)+1\left(x+3\right)$
As, $\left(x+3\right)$ is the common factor of the polynomial,
The polynomial can be factorized as,
$2{x}^{2}\left(x+3\right)+1\left(x+3\right)=\left(x+3\right)\left(2{x}^{2}+1\right)$
Therefore, the factorization of the polynomial $2{x}^{3}+6{x}^{2}+x+3$ is $\left(x+3\right)\left(2{x}^{2}+1\right)$.
