  1. 9
  2. 6
  3. 12

    In front of a school are several gardens in rectangular raised beds. For the area of the rectangular area given, use factoring to find the possible dimensions. Could the garden be square?
    x2 – 4y2

    Here we used the concept of algebriac equations, trinomials and squares to factories the given expression. An expression with variables, constants, and algebraic operations is known as an algebraic expression (like subtraction, addition, multiplication, etc.). Terms comprise expressions. So, the side lengths are x + 2y and x – 2y. So, it has unequal length and width. Then it is a rectangle.
