Answer 1

Step-by-step explanation:

1. x²-3x+6x-18

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

=(x-3)(x+6)

2. x²+6x-21

d=b²-4ac

=36-4x(-21)

=36+84

=100

x=(-b+-√d)/2a

=(-6+-10)/2

x=(-6+10)/2 x=(-6-10)/2

=2 =-8

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))
