Question

I need help I’ve been having trouble with this chapter for about a week

Answer 1

Given:

`3x^2+20x+33`

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*33 \\ =99 \end{gathered}`

The factor of 99 is:

So take factor :

`\begin{gathered} 11\text{ and \lparen3}*3) \\ \\ 11\text{ and 9} \end{gathered}`

Factorization of the equation is:

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