Answers & Solutions:
1) Answer (A)
There can be a solution when
or x=3 and x=2
There can also be a solution when x+1 = 0 or x=-1
Hence three possible solutions exist.
2) Answer: 1
Let
So, the given equation is
So,
If
If
So, the total number of distinct real roots of the given equation is 1
3) Answer (D)
if
For X=6,7 the value
.’. {2,3,4,5,6,7} is the solution set of X.
.’. X can take six values.
4) Answer (C)
We know that,
Since,
=>
Now,
=
=
=
= -x
Hence, option C.
5) Answer (C)
Given that
Sum of two square terms is zero i.e. individual square term is equal to zero.
U =
Therefore,
6) Answer (D)
We know that
Therefore
Therefore,
We know that
Hence,
7) Answer (C)
If
Then x = -5 and x = 2 will give
Substituting x = -5 we get,
Solving we get,
Substituting x = 2 we get,
=>
Solving i and ii we get
a and b
Hence, option C is the correct answer.
8) Answer (C)
as
so equation will be resolved to
9) Answer (B)
It can be clearly seen that if b=1 then
10) Answer (B)
b = sum of the roots taken 2 at a time.
Let the roots be n-1, n and n+1.
Therefore,
We hope this Quadratic Equation Questions for NMAT pdf for NMAT exam will be highly useful for your Preparation.
