The correct answer is B
I. x² - 19x + 84 = 0
II. y² - 25y + 156 = 0
I. 4 x ² - 4 x + 1 = 0
II. 4 y ² + 4 y + 1 = 0
...I. 8x² + 2x – 3 = 0
II. 6y² + 11y + 4 = 0
I. 99x² + 161 x + 26 = 0
II. 26 y² + 161 y + 99 = 0
I. 8x2- 2x – 15 = 0
II. 12y2- 17y – 40 = 0
I.70x² - 143x + 72 = 0
II. 80 y² - 142y + 63 = 0
(i) 2x² + 14x - 16 = 0
(ii) y² – y – 12 = 0
I. 35 y² + 58 y + 24 = 0
II. 21 x² + 37 x + 12 = 0
I. 56x² - 99x + 40 = 0
II. 8y² - 30y + 25 = 0
Equation 1: 2x2 - 21x + 54 = 0
Equation 2: 4y2 - 23y + 15 = 0
Difference between the roots of equation 1 is approx...
