roots: a+b, a-b
quadratic polynomial: x² - (a+b + a-b) x + (a+b)(a-b) = 0
x² - 2 a x + a²-b² = 0
quadratic polynomial: x² - (a+b + a-b) x + (a+b)(a-b) = 0
x² - 2 a x + a²-b² = 0

Given roots : (a + b) and (a - b)
Sum of roots = (a + b) + (a - b) = a + a + b - b = 2a
Product of roots = (a + b)(a - b) = a² - b²
Required quadratic polynomial = k[x² - (sum of roots) + (product of roots)] = 0
= k [ x² - (2a) + (a² - b²) ] = 0
= x² - 2a + (a² - b²) = 0 , where k = constant
Hope This Helps You!
