I. 195x² - 46x - 21 = 0
II. 209y² + 7y - 12 = 0
I. 195x² - 46x - 21 = 0 195x² + 45x - 91x - 21 = 0 15x(13x + 3) - 7(13x + 3) = 0 (13x + 3) (15x – 7) = 0 ∴ x = 7/15, -3/13 II. 209y² + 7y - 12 = 0 209y² + 57y - 44y - 12 = 0 19y(11y + 3) – 4(11y + 3) = 0 (19y – 4) (11y + 3) = 0 ∴ y = 4/19, -3/11 Hence, relationship cannot be established between x and y Alternate Method: Remember whenever constant value of both the quadratic equations are - ve, there is no need to find the exact value of roots. In this case, there will be always no relation between x & y. Hence relationship between x & y cannot be established.
