Question

factorize: x^3-7x-6​

Answer 1

Step-by-step explanation:

x³ - 7x - 6 = 0

According to the rational root theorem, the only possible roots of this equation are ±1 , ±2 , ±3 , and ±6. Using long division or synthetic division to find the factors, we get

(x + 2)(x² - 2x - 3) = 0

(x + 2)(x - 3)(x + 1) = 0
