[]
volunteer
nope
19,385
352

i meant the double negative of the 2
19,385
361
[]
volunteer
6 - (-2)
19,385
362

hey!

What questions do you have?
18,506
2
[]
student
Anything about Radical Equations
18,506
3
[]
volunteer
Do you have a specific example you'd like to go over?
18,506
4
[]
student
x=(x+12)^1/2
18,506
5
[]
volunteer
Cool! Do you have any ideas how to get started, or are you stuck?
18,506
6
[]
student
I am stuck
18,506
7
[]
volunteer
So step 1 is usually ISOLATE THE RADICAL
18,506
8
[]
volunteer
basically get it alone on one side of the equation'
18,506
9
[]
volunteer
But that's already done!
18,506
10
[]
volunteer
Step 2 is to get rid of the radical!
18,506
11
[]
volunteer
What operation undoes a square root?
18,506
12
[]
student
square
18,506
13
[]
volunteer
Right!
18,506
14
[]
volunteer
Let's square both sides so there's no more radical
18,506
15
[]
volunteer
Does that make sense?
18,506
16
[]
student
yes
18,506
17
[]
volunteer
Cool! How would you solve this quadratic equation?
18,506
18
[]
student
make it equal zero
18,506
19
[]
volunteer
Right!
18,506
20
[]
student
this is where I get stuck
18,506
21
[]
volunteer
Watch out with that +12 first!
18,506
22
[]
volunteer
Are you adding or subtracting 12 from both sides of the equation?
18,506
23
[]
student
subtracting
18,506
24
[]
volunteer
Right!
18,506
25
[]
volunteer
So you end up with +12 or -12 on the left side at the end?
18,506
26
[]
student
minus 12
18,506
27
[]
volunteer
Ok!
18,506
28
[]
volunteer
Now you're stuck here?
18,506
29
[]
student
yes
18,506
30
[]
volunteer
Do you remember factoring?
18,506
31
[]
student
yes
18,506
32
[]
volunteer
Can you factor the LHS (left hand side)?
18,506
33
[]
student
yes
18,506
34
[]
volunteer
Nice work! And checking is super important in general, but especially for radicals. It's easy to end up taking the root of a negative number if you don't check your solutions!
18,506
35
[]
volunteer
Perfect!
18,506
36
[]
volunteer
Any questions about the steps to solve that one?
18,506
37
[]
student
I think I understand it now
18,506

Of course! Do you want to share the question to put it up on the whiteboard?

Ok
18,917

Great! Do you have an idea on how to go about this?

Yes, change to point slope form
