I. 88x² - 13 x – 56 = 0

II. 15 y² + 41 y + 28 = 0

I. 88x² - 13 x – 56 = 0 88x² - 77 x + 64 x – 56 = 0 11 x(8 x – 7) + 8 (8x – 7) = 0 (11 x + 8) (8 x – 7) = 0 x = 7/8, -8/11 II. 15 y² + 41 y + 28 = 0 15 y² + 21 y + 20 y + 28 = 0 3 y(5 y + 7) + 4 (5 y + 7) = 0 (3 y + 4) (5 y + 7) = 0 y = -4/3, -7/5 Hence, x>y
