Formula used:
The factors of a polynomial can be find by taking a common factor and this method is called factor by grouping,
Consider the polynomial \(2x^{3}+6x^{2}+x+3\).
This is a four term polynomial, factorization of this polynomial can be find by factor by grouping as,
\(2x^{3}+6x^{2}+x+3=(2x^{3}+6x^{2})+(x+ 3)\)
\(= 2x^{2}(x+3)+1(x+3)\)
As, \((x+3)\) is the common factor of the polynomial,
The polynomial can be factorized as,
\(2x^{2}(x+3)+1(x+3)=(x+3) (2x^{2}+1)\)
Therefore, the factorization of the polynomial \(2x^{3} + 6x^{2}+x+3\) is \((x + 3) (2x^{2}+1)\).
