How do you use synthetic substitution to evaluate x=4 for #P(x)= x^3 - 4x^2 + 4x - 5#?
(see below for synthetic substitution)
line 1: the coefficients of the polynomial terms (in descending order of powers of
line 2: the product of the value of
line 3: just a pretty line to keep things in place
line 4: the sum of the the values in this column in lines 1 and 2
The final sum (in line 4) is the value of the polynomial at the required value of
