Activity 2 Determine the indicated product in each of the following. Then answer the questions that follow. 1)
(x +3)(x +3)
2)
(x – 2)(x – 2)
3)
(3x +1)(3x + 1)
4)
(2x + 3)2
5)
(3x – 2)2
How did you find each product?
What mathematics concepts or principles did you apply to come up with each product?
How did you apply these concepts or principles in finding each product?
What observations can you make about the product?
Did you find any pattern in determining each product? Describe the pattern, if there is any.
Is there an easy way of finding each product without using the distributive property method or the FOIL method? Explain your answer.
C. Firm – up
:
How can we obtain the product of similar binomials?
Example: Multiply: (x + 5)2
(x + 5)2
=
(x + 5) (x + 5) F
O
I
=
x2 + 5x + 5x + 25
=
x2 + 10x + 25
L
Notice the patterns that appear in the example.
Here x is the first term and 5 is the second term
(x + 5)2
=
x2 + 10x + 25
x2 is the square of the first term of the binomial (x)2 = x2
10x is twice the product of the terms 2(5x) = 10x
25 is the square of the second term (5)2 = 25
This patterns leads to the formula for the square of binomial:
(a + b)2
=
(a + b) (a + b)
=
a2 + 2ab + b2
To square a binomial, square the first term, get twice the product of the terms and finally square the second term.
Activity 3 Find each indicated product then answer the questions that follow. 1)
(x + 9)(x + 9)
2)
(2x – 2)(2x – 2)
3)
(3x +y)(3x + y)
4)
(3m + 1)2
5)
(4b + a)2
How do you find each product now?
Is it easier than using the FOIL method? Why?
IV.ASSIGNMENT:
Use special product in multiplying the following. 1)
(x - 4)(x - 4)
2)
(m + 7)(m + 7)
3)
(x + y)(x + y)
4)
(m + 6)2
5)
(b + 3a)2
