<span>8d – 4d – 6d – 8 = 2d
Combine common terms:
-2d - 8 = 2d
Add 2d to both sides:
-8 = 4d
Swtich sides:
4d = -8
Divide both sides by 4:
d = -2
Answer: - 2

Step-by-step explanation:
x⁴ − 5x³ + 11x² − 25x + 30
x⁴ − 5x³ + 6x² + 5x² − 25x + 30
x² (x² − 5x + 6) + 5 (x² − 5x + 6)
(x² + 5) (x² − 5x + 6)
(x² + 5) (x − 2) (x −3)
The zeros are 2, 3, and ±√5i.
