Question
I. 2x² + 15 x - 27 = 0 II. 3 y² + 25 y
- 18 = 0Solution
I. 2x² + 15 x - 27 = 0 2x² - 3 x + 18 x - 27 = 0 x (2 x – 3) + 9 (2 x – 3) = 0 (x + 9) (2 x – 3) = 0 x = - 9, 3/2 II. 3 y² + 25 y - 18 = 0 3 y² - 2 y + 27 y - 18 = 0 y (3 y – 2) + 9 (3 y – 2) = 0 (y + 9) (3 y – 2) = 0 y = - 9, 2/3 Hence, relationship cannot be established between x and y.
