Answer:
So the roots of the polynomial are -7 , 4 , 2
Step-by-step explanation:
Given the polynomial in the question
5x³ + 5x² - 170x + 280
One of the factor of this polynomial is (x + 7)
By using remainder theorem
5x²-30x+40
-----------------------------------
x+7 | 5x³ + 5x² - 170x + 280
5x³ + 35x²
----------------------------
-30x² -170x + 280
-30x² -210x
------------------
40x + 280
40x + 280
----------------
0
So the polynomial we have is
5x²- 30x + 40
divide by 5
x² - 6x + 8
(x-4)(x-2)
So the roots of the polynomial are -7 , 4 , 2
