Answers
Given: Two equations: x³ - 3x² - 9x - 5 and x + 1
To find: Divide x³ - 3x² - 9x - 5 by x + 1
Solution:
- So we have a polynomial x³ - 3x² - 9x - 5 which will be divided by x + 1.
x + 1 ) x³ - 3x² - 9x - 5 ( x²- 4x - 5
x³ + x²
(- - )
-4x² - 9x - 5
-4x² - 4x
(+ + )
-5x - 5
-5x - 5
(+ + )
0
- So the remainder comes out to be 0.
Answer:
So in solution part, we have divided x³ - 3x² - 9x - 5 by x + 1.
