Question
I. 6 y² + 11 y – 7= 0 II. 21 x² +
5 x – 6 = 0Solution
I. 6 y² + 11 y – 7= 0 6 y² + 14 y - 3 y– 7= 0 2 y(3 y + 7) – 1(3 y + 7) = 0 (2 y – 1)(3 y + 7) = 0 y = 1/2,- 7/3 II. 21 x² + 5 x – 6 = 0 21 x² + 14 x - 9 x – 6 = 0 7 x(3 x + 2) – 3(3 x + 2) = 0 (7 x – 3)(3 x + 2) = 0 x = 3/7, -2/3 Hence, relationship cannot be established between x and y
