Two quadratic equations are given. Find the roots and mark the right relation. I. $x^{2} - 20 x + 99 = 0$
II. $y^{2} - 14 y + 45 = 0$

Question

Two quadratic equations are given. Find the roots and mark the right relation. I. x^2 - 20x + 99 = 0 II. y^2 - 14y + 45 = 0

Accepted Answer

x ≥ y. I: (x − 9)(x − 11) = 0, so x = 9 or 11. II: (y − 5)(y − 9) = 0, so y = 5 or 9. The smallest x (9) equals the largest y (9), so x ≥ y.
