Explanation

x^2 + 10x + 25 = 0 -> (x+5)^2 = 0 -> x = -5. 6y^2 - 19y + 10 = 0 -> 6y^2 - 15y - 4y + 10 = 0 -> 3y(2y-5) - 2(2y-5) = 0 -> (3y-2)(2y-5) = 0 -> y = 2/3 or 5/2. Since -5 < 2/3 and -5 < 5/2, x < y.

AI explanation

The first equation x^2 + 10x + 25 = 0 is a perfect square, which factors to (x + 5)^2 = 0, giving the single root x = -5. For the second equation 6y^2 - 19y + 10 = 0, factoring yields (2y - 5)(3y - 2) = 0, giving the roots y = 5/2 and y = 2/3. Comparing the values, x = -5 is strictly less than both positive values of y. Therefore, the relationship x < y holds true.
