Given that,
We have to factor out terms and write as a product of 2 binomials and monomial
A monomial is a mathematical expression with only one term, while a binomial is a mathematical expression with two terms.
From given expression,
3 and a are common factors in second bracket
Hence, the product of two binomial is written in two binomial and a monomial
