Directions (11-15): In these questions, two equations numbered I and II are given. You have to solve both the equations and give answer:
Q11. I. x² – 9x + 18 = 0
II. 5y² – 22y + 24 = 0
x² – 6x – 3x + 18 = 0
x (x – 6) –3 (x -6) = 0
(x – 3) (x – 6) = 0
x= 3, 6
II. 5y² – 22y + 24 = 0
5y² – 10y – 12y + 24 = 0
5y (y- 2) –12 (y – 2) = 0
(y – 2) (5y – 12) = 0
y = 2, 12/5
∴ x > y
Q12. I. 6x² + 11x + 5 = 0
II. 2y² + 5y + 3 = 0
6x² + 6x + 5x + 5 = 0
6x (x + 1) + 5 (x + 1) = 0
(x+ 1) (6x +5) = 0
x=-1,-5/6
II. 2y² + 5y + 3 = 0
2y² + 2y + 3y + 3 = 0
2y (y+ 1) + 3 (y+ 1) = 0
(y+ 1) (2y + 3) = 0
y= -1,-3/2
∴x≥y
Q13. I. x² + 10x + 24 = 0
II. y² – √625=0
x² +6x + 4x + 24 = 0
x (x + 6) +4 (x+ 6) = 0
(x + 4) (x + 6) = 0
x = –4, –6
II. y² – √625=0
y²=√625
y² = 25;
y= ±5
∴ Relationship between x and y cannot be determined
Q14. I. 10x² + 11x + 1 = 0
II. 15y² + 8y + 1 = 0
10x² + 10x+ x+ 1 = 0
10x (x + 1) + 1 (x + 1) = 0
(x + 1) (10x + 1) = 0
x= -1,-1/10
II. 15y² + 8y + 1 = 0
15y² +5y + 3y + 1 = 0
5y (3y + 1) + 1 (3y+ 1) = 0
(3y + 1) (5y + 1) = 0
y=-1/3,-1/5
∴ Relationship between x and y cannot be determined
Q15. I.15x² – 11x + 2 = 0
II. 10y² – 9y + 2 = 0
15x² – 5x – 6x + 2 = 0
5x (3x – 1) – 2 (3x – 1) = 0
(3x – 1) (5x – 2) = 0
x=1/3,2/5
II. 10y² – 9y + 2 = 0
10y² – 5y – 4y + 2 = 0
5y (2y – 1) –2 (2y – 1) = 0
(2y – 1) (5y - 2) =0
y=1/2,2/5
∴ x ≤ y
