3

+4a−3

To find:

Factor=?

Solution:

The above-given equation can't be factorized because it takes a to the power 3.

Example of the factor can be defined as follows:

\begin{gathered}\to a^2+4a+3\\\\\to a^2+3a+a+3\\\\\to a(a+3)+1(a+3)\\\\\to (a+1)(a+3)\\\end{gathered}

→a

2

+4a+3

→a

2

+3a+a+3

→a(a+3)+1(a+3)

→(a+1)(a+3)
