Directions (Q. 1–4): In each of these questions, two equations numbered I and II with variables x and y are given. You have to solve both the equations to find the value of x and y. Give answer
1) if x > y
2) if x >= y
3) if x < y
4) if x <= y
5) if x = y or relationship between x and y cannot be determined.
1.
I. x^2 + 8x + 15 = 0
II. y^2 – 12y + 32 = 0
2.
I. 4x^2 + 20y + 25 = 0
II. 4y^2 + 12y + 9 = 0
3.
I. 42x^2 + 89x + 45 = 0
II. 32y^2 + 4y – 21 = 0
4.
I. 12x^2 – 13x + 3 = 0
II. 8y^2 + 22y – 21 = 0
