here is your answer

Answer 2

Given,

An expression x^2+9x+18x

2

+9x+18 .

To find,

Factors of x^2+9x+18x

2

+9x+18

Solution,

It can be done by middle-term splitting as follows :

\begin{gathered}x^2+9x+18=x^2+(6+3)x+18\\\\=x^2+6x+3x+18\\\\=x(x+6)+3(x+6)\\\\=(x+3)(x+6)\end{gathered}

x

2

+9x+18=x

2

+(6+3)x+18

=x

2

+6x+3x+18

=x(x+6)+3(x+6)

=(x+3)(x+6)

Hence, the factors of x^2+9x+18x

2

+9x+18 are (x+3) and (x+6).
