x^2 -(sum of roots)x + product of roots = 0
x^2 - (2√7 - 2√7)x - 28 = 0
x^2 - 0x - 28 = 0
x^2 - 28 = 0

a+ b= 2√7 -2√7
= 0
ab. = 2√7 x -2√7
= -28.
quadratic equation
= x^2 - (a+b)x + ab
= x^2 - (0)x + (-28)
= x^2 -28.
= 0
ab. = 2√7 x -2√7
= -28.
quadratic equation
= x^2 - (a+b)x + ab
= x^2 - (0)x + (-28)
= x^2 -28.
