Find-:

Factorization of the equation.

Sol:

A simple method of factorization is to multiply in first and last order then break it down into parts to make the middle number then.

\begin{gathered} =3\times33 \\ =99 \end{gathered}

The factor of 99 is:

So take factor :

\begin{gathered} 11\text{ and \lparen3}\times3) \\  \\ 11\text{ and  9} \end{gathered}

Factorization of the equation is:

\begin{gathered} =3x^2+20x+33 \\  \\ =3x^2+11x+9x+33 \end{gathered}
