Question

factorise
please give me the answer ​

Answer 1

Step-by-step explanation:

$x {}^{2} + 9x + 18 = 0$

We can split the middle term

${x}^{2} + 6x + 3x + 18 = 0$

x (x +6) + 3 (x + 6 ) = 0

(x + 6)(x + 3) = 0

x = -6 & -3

Answer 2

Answer:

(x+6)(x+3)

Step-by-step explanation:

x^2 + 9x +18

so it can be written as

x^2 +6x+3x+18

×(x+6)+3(x+6)

so

(x+6)(x+3)
