Answer:
a=-5
b=4
c=-1
d=0
Step-by-step explanation:
The given cubic equation is of the form;
When x=0 and y=0, we get:
when x=1 and y=-2, we get:
When x=2 and y=-26, we get:
When x=3 and y=-54, we get:
We need to solve the system:
From the top equation:
Put this expression into equation 2 and 3
also
Now we solve the system:
subtract the top equation from the down one to get:
This implies that:
and
