Question

and the product
What is the quadratic pohnomial the sum of whose zeroes is
2
of the zeroes is -1.​

Answer 1

Answer:

x^2 -2x -1 = 0

Step-by-step explanation:

sum of zeroes ,(α+β) = 2

product of the zeroes ,(αβ) = -1

hence quadratic polynomial ,

= x^2 - (α+β)x + (αβ) = 0

=x^2 -2x -1 = 0
