Question
Find the product. (x – 12)(x + 12)
- x2 – 144
- x2 + 144
- x2 + 12x + 144
- x2 – 12x + 144
The correct answer is: x2 – 144
Using the pattern (a + b)(a – b) = a2 – b2,
(x + 12)(x – 12) = x2 – 122 = x2 – 144

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.

x2 + 32x + 256
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 length is (x + 16) and all the sides are equal in length. So, it is a square.
