Answer 2

Answer:

Step-by-step explanation:

Given:- x= 1/2 ; y= -1

Sum of zeroes = x+y= 1/2+(-1) = -1/2

Product of zeroes = xy = 1/2 × (-1) = -1/2

Now ;

Equation for quadratic polynomial = x^2 - (sum of zeroes)x + (product of zeroes)

= x^2 - (-1/2)x + (-1/2)

= x^2 + (1/2)x - 1/2

Or

2x^2 + x - 1
