3. Mini Lesson
S Another word for the square root of a number is
saying radical _______(insert number).
S 5 = radical 5
S 4 = radical 4
6. Problem 1
7
6
The first thing we need to do is get rid of the 6. As explained
in the previous presentation, another way to completely get
rid of something squared is to multiply it by itself. But to do
this we also have to multiply the rest of the problem by
radical 6.
7 6 7 6 7 6 This is the final answer
since the instructions were
6 x 6
= 36 = 6 to get rid of the
denominator’s square
11. Problem 2
7 14 + 21 – 4 14
The first step is to see if any of the square roots can be
simplified.
Unfortunately, they can’t.
12. Problem 2
7 14 + 21 – 4 14
The next step is to combine the like square roots (remember
combing like terms).
Combining the terms:
7 14 + - 4 14 = 3 14
Now the problem looks like 3 14 + 21
20. Problem 4
( 2 + 5 )( 3 – 3 5 )
To solve the problem we need to use F.O.I.L.
( 2 + 5 )( 3 – 3 5 )
6 – 3 10 + 15 – 3 25
21. Problem 4
6 – 3 10 + 15 – 3 25
Now we need to simplify everything
6 – 3 10 + 15 – 15
After this you would need to add the like terms if there were
any.
