Question

find a qiadratic polynomial ,if the zeroes of it are 2 and -1​

Answer 1

Answer:

Required polynomial = x² + 2x - 1

Step-by-step explanation:

→ Given zeroes = 2 , -1

→ Therefore, Sum of zeroes (α + β) = 2

→ Also, Product of zeroes (αβ) = -1

→ Now, for the finding the quadratic polynomial,

→ x² + (α + β)x + αβ

→ x² + (2)x + (-1)

→ x² + 2x - 1
