Question

use synthetic division to find the result when 2x^3+9x^2+16x+18 is divided by x+1. if there is a remainder,express the result form q(x) +r(x)/b(x)

Answer 1

q(x) = 2x² +7x +9

r(x) = 9

b(x) = x+1

Explanation:

(2x^3+9x^2+16x+18) / (x+1) = 2x² +7x +9 + (9) / (x+1)

-1 | 2 9 16 18

↓ -2 -7 -9

--------------------

2 7 9 9

x² x .. R

Answer 2

2x^2+7x+9 the remainder is the 9
