2. Introduction
The first question that we will be asking is what is a
trinomial?
• In elementary algebra, a trinomial is
a polynomial consisting of three terms or monomials.
The second question that we will be asking is what are
trinomial tiles?
• Algebra tiles can be used to visualize how a perfect
square trinomial can be formed.
The tiles could be used by students or simply used by
the teacher as a warm-up to this concept.
3. Example
Example 1: What is needed to
create a perfect square trinomial for:
• Use the algebra tiles to create
a square. What tiles will be needed
to complete the square?
• After viewing several examples,
help students to see the pattern for
finding the needed constant
term. "Take half of the coefficient of
the x-term and square it.“
4. Conclusion
Life is good for only two things, discovering
mathematics and teaching mathematics.
