SOLUTION: 1. If the area of a square garden is (x 2 + 8x + 16) sq units, is it possible to find the measure of its side? Why? Or why not? How? 2. If the area of a garden is (3x 2

Question 622680: 1. If the area of a square garden is (x
2
+ 8x + 16) sq units, is it possible to find the measure of its side? Why? Or why
not? How? 2. If the area of a garden is (3x
2
+ 8x + 4) sq units, is it possible to find the measure of the side? Is the garden a
square? Why? Or why not?
3. Is x
2
� y
2
= (x � y)
2
? Explain why or why not. If you do not understand the rules on factoring , what
do you think will happen?
4. What is the difference of the squares of 105 and 5 ? What is the square of their difference?
5. Explain or illustrate how you can find the difference of the squares of two terms using 105 and 5.

1. Factor:

Yes because the given quadratic expression is a perfect square which can be shown by factoring.
2. Factor:
Yes! The sides are and and the garden is not a square because the sides are not equal.
3. Is ?
To find out, expand the right side:
=

So
4.
a) =
b) =
5. Use the identity:
and if a = 105 and b = 5, then...
=
