Answer 2

Answer:

Quadratic polynomial is x² - 2x - 1 = 0

Step-by-step explanation:

The general quadratic polynomial is written as:-

x² - (sum of the roots)x + product of the roots = 0  ........... (1)

Given sum is 2 and product -1 .

now, put these value in equation (1),

x² - (2)x + (-1) = 0

x² - 2x - 1 = 0

hence, quadratic polynomial is x² - 2x - 1 = 0
