Method 1:
Find the easiest term.
In this case is C then B then A
Sub x=1 to get C=-4
Sub x=0.5, C=-4 to get B=1.75
Sub x=-3, C=-4 to get A=3
Method 2:
Expand the rhs equation.
Then compare the coefficient of x^2, x and constant to create 3 equations.
Use simultaneous equation to solve for A, B and C.
