A side of the original square is 4 feet.
Answer:
The quadratic equation is: 
Step-by-step explanation:
If the roots of the quadratic equation are "-6" and "6", then it must have the following factors: 
Therefore, we can write the equation in factor form as:

where a is a real number constant factor. Now, this equation in standard form will look like:

Therefore, using the information about the leading coefficient being "1" (one), we derive that the constant factor
must be "1". The final expression for the quadratic becomes:
