Question

Factorise:

x²-3x-18 ​

Answer 1

x² - 6x + 3x - 18

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

( x + 3 ) ( x - 6)

I hope this will be help you

Answer 2

Step-by-step explanation:

Given: x

2

−3x−18

=x

2

−6x+3x−18, (split the middle term)

=(x

2

−6x)+(3x−18), (group the pair of terms)

=x(x−6)+3(x−6), (factor each binomials)

=(x−6)(x+3), (factor out common factor (x−6))

hopefully it will work ☺️
