Factoring Perfect Square Trinomials

2. At the end of the lesson, you
should be able to:
▪ determine patterns in factoring
polynomials; and
▪ factor perfect square trinomials and
general trinomials completely.

3. Throwback!
Patterns in squaring a binomial:

4. Remember me!
Following the pattern in squaring a
binomial, fill-in the missing term.
1.

5. is Perfect Square Trinomial

6. Perfect Square Trinomial are
algebraic expressions with three
terms that are created by
multiplying a binomial to itself.
*Recognizing when you have these perfect square trinomials
will make factoring them much simpler.

7. Perfect yarn???
Determine whether the given
expressions are perfect square
trinomials.

8. To factor a perfect square
trinomial,
1. Examine whether the first term
and last term are perfect squares.
2. Look at the middle term. Check
whether it is twice the product of
the square root of the first term
and last term.

9. To factor a perfect square
trinomial,
3. If conditions 1 and 2 were satisfied
then, the expression is a perfect
square trinomial.
4. Factor completely the given
trinomial following the pattern .
