ANSWER
![2 \frac{1}{4}](https://tex.z-dn.net/?f=2%20%5Cfrac%7B1%7D%7B4%7D%20)
EXPLANATION
We want to find the constant that must be added to
![{x}^{2} - 3x](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20-%203x)
to form a perfect square.
Comparing the given expression to
![a{x}^{2} + bx + c](https://tex.z-dn.net/?f=%20a%7Bx%7D%5E%7B2%7D%20%20%2B%20bx%20%2B%20c)
we have
a=1 , b=-3 , and c=0.
We need to add
![{( \frac{b}{2a} })^{2}](https://tex.z-dn.net/?f=%20%7B%28%20%5Cfrac%7Bb%7D%7B2a%7D%20%7D%29%5E%7B2%7D%20)
We substitute the values to get,
![{( \frac{ - 3}{2(1)} })^{2} = \frac{9}{4}](https://tex.z-dn.net/?f=%7B%28%20%5Cfrac%7B%20-%203%7D%7B2%281%29%7D%20%7D%29%5E%7B2%7D%20%20%3D%20%20%5Cfrac%7B9%7D%7B4%7D%20)
We change this to mix numbers to get,
![2 \frac{1}{4}](https://tex.z-dn.net/?f=2%20%5Cfrac%7B1%7D%7B4%7D%20)
The last choice is correct.
