Answer:

Hey mate here is your answer...

Step-by-step explanation:

х4 + x3 - 8x2 - 9x – 9 = 0.

Разложим одночлены в сумму нескольких:

х4 - 3x3 + 4х3 - 12x2 + 4х2 - 12x + 3х – 9 = 0,

сгруппируем слагаемые:

(х4 - 3x3) + (4х3 - 12x2) + (4х2 - 12x) + (3х – 9) = 0,

выносим общий множитель:

(х – 3) х3 + (х – 3) * 4х2 + (х – 3) * 4х + (х – 3) * 3 = 0,

выносим общий множитель:

(х – 3) (x3 + 4x2 + 4x + 3) = 0.
