Answer:
thats not a cubic formula....
putting 1,
-3
putting 2,
3
putting 3,
9.......
......
follow me guys.....
Step-by-step explanation:
putting 1,2,3 as x in -6x+12x-9 and if we get 0 then they are zeros
-6(1)+12(1)-9
=-6+12-9
=-3
therefore 1is not a zero .
-6(2)+12(2)-9
=-12+24-9
=3
therefore 2 is also not a zero
-6(3)+12(3)-9
-18+36-9
9
therefore it is also not a zero.
