Candy draws a square design with a side length of x inches for the window at the pet shop. She takes the design to the printer and asks for a sign that has an area of 16x2 – 40x + 25 square inches. What is the side length, in inches, of the pet shop sign?
Answer:
the length of the sign is  inches
 inches
Step-by-step explanation:
Given 
Area of the square of design = 
First we find the roots of equation 
The roots of the quadratic equation  are given by
 are given by 

where 






That is, the factors of the polynomial  are
 are  and
 and  .
.
So, Area of the square design =  =
 = 
Area of a square = Length^2
Thus, the length of the sign is  inches
 inches
