Given :
Set of x-intercepts {-3,1,7},
point through which it passes (-2,54)
Now,
Step 1: Substitute value of x intercepts in equation, , we get,
... equation (1)
Step 2: substitute x an y with the point through which it passes,
∴
Step 3: Now, substituting value of a in equation (1), we have
(Requited cubic equation)
