Question
I.70x² - 143x + 72 = 0 II. 80 y² - 142y + 63 =
0Solution
I. 70x² - 143x + 72 = 0 70x² - 63x - 80 x + 72 = 0 7x(10 x – 9) – 8(10 x – 9) = 0 (7x – 8) (10 x – 9) = 0  ∴x = 9/10 ,8/7 II. 80 y² - 142y + 63 = 0 80 y² - 70 y - 72y + 63 = 0 10y(8 y – 7) – 9(8 y – 7) = 0 (10 y – 9) (8 y – 7) = 0 ∴y = 9/10 ,7/8 Hence,  x≥y.
