Question

Use synthetic substitution to evaluate the polynomial for the given value x = -3.
P(x) = x3 + 3x2 + 4
P(-3) =

Answer 1

Do you know how to set up the coefficients of P(x) for synthetic division?

Answer 2

Nobody is looking. It's okay to write something. I just need to know where to begin.

Answer 3

P(x) = 1 x^3 + 3 x ^2 + 0x + 4
So, the coefficients for the synthetic division will be: 1 3 0 4

Note that if there is a gap in the powers of x as in this problem (there's no shown x term) then you must account for its coefficient of 0 as in 0x.
