Question

Divide x^4 + 7 by x - 3.

a.) x³ - 3x² - 9x - 27 R 88
b.) x³ + 3x² + 9x - 27 R -74
c.) x³ + 3x² + 9x + 27 R 88

Answer 1

Answer:

c

Step-by-step explanation:

Divide using synthetic division, remembering to place a zero to denote the terms x³, x² and x

Since division by (x - 3) then evaluate using h = 3

3 | 1  0  0  0  7

    ↓

    1    3  9  27 81

   ----------------------

    1  3  9  27  88 ← degree 3 polynomial

quotient = x³ + 3x² + 9x + 27 , remainder = 88 → c
