What is the remainder when 3 is synthetically divided into the polynomial - x^2 + 5x - 9?

A: 0

B: - 3

C: - 6

D: 5

Take the coefficients of each term and list them.

- 1 5 - 9

Multiply 3 by the first coefficient and combine it from the second.

- 1 * 3 = - 3, 5 - 3 = 2

Multiply 3 by this product and combine it from the third term.

3 * 2 = 6, - 9 + 6 = - 3

Your remainder is option B, - 3.
