Question
I. 35 y² + 58 y + 24 = 0 II. 21 x² + 37
x + 12 = 0Solution
I. 35 y² + 58 y + 24 = 0 35 y² + 30 y + 28 y + 24 = 0 5 y(7 y + 6) + 4 (7 y + 6) = 0 (5 y + 4) (7 y + 6) = 0 y = -4/5, -6/7 II. 21 x² + 37 x + 12 = 0 21 x² + 9 x + 28 x + 12 = 0 3 x (7 x + 3) + 4 (7 x + 3) = 0 (3 x + 4) (7 x + 3) = 0 x = -4/3, -3/7 Hence, relationship cannot be established between x and y.
