Question

Write the quadratic polynomial whose summer of zeros is 3 and sum of squares of zeros is 7

Answer 1

Answer:

2y^2-6y+3

Explanation:

if the zeroes are x and y

given,

x+ y= 3 --------(1)

x^2+y^2=7 ------(2)

x = 3-y

put the x value in (2)equation

(3-y)^2+y^2=7

9+y^2-6y+y^2=7

2y^2-6y+3=0

: quadratic equation is 2y^2-6y+3=0
