# What is the Value of Q ?

If ( x – 2 ) is a factor of X^{2} + 3Q X– 2Q, then the value of Q is

- 2
- -2
- 1
- -1

**Answer: (4) -1**

**Explanation:-**

X – 2 or X = 2

X^{2} + 3QX – 2Q

Put the value of X in the given equation,

2^{2} + 3Q x 2 – 2Q = 0

4 + 6Q – 2Q = 0

4Q = -4

Q = -1

Hence, the answer is (4) -1
