Answer : 
Given expression is 
To make perfect square trinominal we use completing the square method
In completing the square method we add and subtract the half of square of coefficient of middle term 
Here coefficient of middle term is -7
Half of -7 is 
Square of  is
 is  =
 =  
 
So the expression becomes ![x^2 - 7x +  [tex] \frac{49}{4}](https://tex.z-dn.net/?f=%20%20x%5E2%20-%207x%20%2B%20%20%5Btex%5D%20%5Cfrac%7B49%7D%7B4%7D%20%20) that gives perfect square trinomial
 that gives perfect square trinomial
Hence , the value of 'c' is
