Step-by-step explanation:

u have to split the middle term and take out common

x^2+9x+18

x^2+5x+3x+18

x(x+5)+3(x+5)

(x+3)(x+5)

therefore, x+3=0  &   x+5=0

Answer 2

Answer:

On comparing with standard quadratic equation that is ax2 + bx + c.

Let us simplify the given expression, we get

x2 + 9x + 18 = x² + 6x + 3x + 18

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

= (x + 6) (x + 3)
