An example of system utilization of not linear equations in the daily
life is the employment of quadratic equations. Across the same ones, the
carpenters and other professionals use them to optimize the area of a space
with perimeter and certain dimensions. For example in real life we could have
an example of a room, which measures, the length should be 2 meters bigger than
his width. This might be represented across the following equation of the
second degree
A=W*(W+2) =W*W+2*W
