IMPORTANT QUESTIONS OF Quadratic Equations

Most aspirants are unlikely to disagree with the fact that it’s quantitative ability that is pivotal in most of the competitive examinations. In recent times it has got more prominence considering the fact that the cut-off has grown exponentially and it’s Mathematics that can help you secure the maximum marks provided correct approach and strategies are applied.

We make our best efforts to analyze and segregate those questions which are either based on new patterns or frequently repeated in last few years. Sincere efforts are required to be made to make sure these sums are solved within stipulated time because time management plays vital role in any exam particularly in Banking exams. There is prominent evidence to suggest that only precise strategies together with practicing relevant sums can help you break the cut-off barrier.

In other words, it’s not only how you solve but what you solve too can be deciding factor, that’s why we have attached some of the most prominent questions of Quadratic equation. Feel free to clarify, if you have any query, your inputs are always welcome.

Directions: In the following questions, two equations numbered are given in variables a and b. You have to solve both the equations and find out the relationship between a and b. Then give answer accordingly-

A) a > b
B) a < b
C) a ≥ b
D) a ≤ b
E) a = b or relation cannot be established

1.I. 8/√a + 9/(√a +1) = 7,
II. 9/√b – 3/√b = 2

2.I.9/√a + 3/√a = √a + 1,
II. 4b2+ 5b – 6 = 0

3.I. 6a2+ 13a + 6 = 0,
II. 6b2– b – 2 = 0

4. I. 3a2 + 14a – 5 = 0,
II. 3b2 – 11b + 6 = 0

5.I. 6a2+ 5a – 1 = 0,
II. 3b2– 10b + 3 = 0

6.I. 12a2– 5a – 3 = 0,
II. 3b2– 11b + 6 = 0

7.I. 6a2+ 7a + 2 = 0,
II. 15b2– 38b – 40 = 0

8.I. 3a2– 25a + 52 = 0,
II. 2b2– 7b + 3 = 0

9.I. a2= 1296,
II. b = √1296

10.I. a2– √3969 = √6561,
II. b2– √1296 = √4096
