Question

Q) Factorise:- x²+9x+18 ? ​

Answer 1

Step-by-step explanation:

x² + 9x + 18

x² + 3x + 6x + 18

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

(x+6) (x+3)

so, x= -6, -3

the solutions are :-

x= -6, -3

Answer 2

Answer:

Hence factorisation of given expression will be (X+3)(X+6)

Step-by-step explanation:

In context to questions asked

We have to determine the factors of given expression

As per questions

We have

${x}^{2} + 9x + 18$

So for factorising it we will split the middle terms

Thus we will get

${x}^{2} + 9x + 18 \\ = > {x}^{2} + 6x + 3x + 18 \\ = > x(x + 6) + 3(x + 6) \\ = > (x + 3)(x + 6)$
