Step-by-step explanation:
Given the following equation:
You need to find the value of "x" in order to find the side measure of the original square photo.
Knowing that:
You can expand the equation:
The next step is to subtract 256 from both sides of the equation:
Now you can factor the quadratic equation. Find two numbers whose sum is 20 and whose product is -156. These are 26 and 6:
Choose the positive value.
Therefore, the dimensions of the original square photo were:
