Question

Find all the zeroes of the polynomialएक्स क्यूब+3 x square - 2 x - 6 ​

Answer 1

Given cubic polynomial,

↪ x³ + 3x² - 2x - 6 = 0

Let,

• a = 1
• b = 3
• c = -2
• d = -6

⟹ α + ß + γ = -b/a = -3/1 = -3

⟹ αß + ßγ + αγ = c/a = -2/1 = -2

⟹ αßγ = -d/a = -(-6)/1 = 6

Hence, it is solved....
