Compare x and y given I. x² − 15x + 54 = 0 II. y² − 21y + 108 = 0.

Question

Accepted Answer

x ≤ y. I: (x − 6)(x − 9) = 0, so x = 6 or 9. II: (y − 9)(y − 12) = 0, so y = 9 or 12. Every x is at most every y, and x = y = 9 is possible, so x ≤ y.

Compare $x$ and $y$ given I. $x^{2} - 15 x + 54 = 0$
II. $y^{2} - 21 y + 108 = 0$ .
