Quadratic Equations for SBI PO/Clerk 2018: 01 May
Directions (Q. 1-10): In each of these questions, two equations (I) and (II) are given. You have to solve both the equations and 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 can’t be established.
1. I. x2+ 6x – 112 = 0 II. y2 – 11y + 30 = 0
2. I. x2– 20x – 96 = 0 II. y3 = √21952
3. I. 4x + 8y = 8 II. 6x + 4y = 42
4. I. 6x2– 41x – 30 = 0 II. 5y2 – 40y – 45 = 0
5. I. 4x2– 14x + 12 = 0 II. 6y2 – 20y + 16 = 0
6. I. 7x2– 33x + 20 = 0 II. 7y2 + 9y – 10 = 0
7. I. 7x + 3y = 8 II. 3x + 2y = 12
8. I. x2= 289 II. y = 3√2197
9. I. 8x2– 11x + 3 = 0 II. y2 – 8y + 7 = 0
10. I. x = √1089 II. y2 + y – 756 = 0
