Answer 1

When x=1

x(x-3)+2

=1(1-3)+2

=1×(-2)+2

=-2+2=0

When x=-1

-1(-1-3)+2

=-1×-4+2

=4+2=6

When x=2/3

2/3(2/3-3)+2

=2/3×(-7/3)+2

=-14/9+2=4/9

When x=-1/2

=-1/2(-1/2-3)+2

=-1/2×-7/2+2

=7/4+2=15/4

Hope it helped you!

Answer 2

✍︎ANSWER✍︎

(x-1) (x-2) (x-3) => {(x-1) (x-2)} (x-3)

{x^ 2 - 2x - x + 2} (x-3)

{x^ 2 - 3x + 2} (x-3)

x^ 3 - 3x ^2 + 2x - 3x ^2 + 9x - 6

x& 3 - 6x ^2 + 11x - 6
