Answer:
Step-by-step explanation:
Let the first zero be α = √3 and the second zero be β = -√3
The polynomial is given to be : 2x³ + x² - 6x - 3
Now, The equation containing the two zeros can be formed as :
x² + (α + β)x + α·β = 0
⇒ x² + (√3 - √3)x + √3 × -√3 = 0
⇒ x² - 3 = 0
Now, divide the given polynomial by this equation and note down the resultant quotient.
So, The quotient comes to be 2x + 1
But, since this is the equation formed by zero so this must be equal to 0
