Finding the square consant

Question: How do we find the square constant?

A constant is a number on its own, or sometimes a letter such as a, b or c to stand for a fixed number.  In equations that can be shown like x^2+bx+c, c mostly represents square constants which are constants that helps the equation factor-able: (x+b)(x+b). In some situations the c or the square constant is missing in order to find this constant all you have to do is follow these simple steps:

1. Observe the equation
 x^2+6x+___.

2. Divide 6 by 2 also shown as the b constant in the equation x^2+bx+c
      6/2=3

3. You then multiply 3 by itself as shown below:
     3*3=9

4. The finale answer is : x^2+6x+9 so the missing square constant is 9  

Try it Yourself:
x^2+___=16x
