To show this, Let
==>
, and

Subtracting the 1st from the 2nd, we get
<==> 9 = 3a - 2ah
Subtracting the 2nd from the 3rd, we get
<==> 36 = 12a - 4ah, or 9 = 3a - ah.
Now we have the equations 9 = 3a - 2ah, and 9 = 3a - ah.
subtracting the first from the second, we get ah = 0.
Since , we have h = 0.
Substituting h = 0 into and , we get
3 = a + k and 12 = 4a + k.
From this we get a = 3.
Finally putting h = 0 and a = 3 into , we get k = 0.
