The value of a is .

Step-by-step explanation:

The given expression is

A quadratic expression is complete square if

For the given expression a=a,b=1 and c=3.

Add 12a on both sides.

Divide both sides by 12.

Therefore, the value of a is .

Step-by-step explanation:

We have been given an expression . We are asked to complete the square for the given expression.

First of all, we will factor our a as:

Now, we need to add and subtract half the square of the middle term, that is :

Therefore, our required square would be .
