## Part 1

In this video, we are going to look at solving equations by taking the square root.

For example:

If we are given the equation

we can solve for x by taking the square root of both sides.

This will leave us with just x. However, the square root of 9 isn’t just 3. It can be positive or negative 3. So

If we had something more complicated like

then we would first have to get the by itself. So, first add 5 to both sides to isolate the . Now we are left with . Then take the square root of both sides

## Part 2

In this video, we are going to look at solving equations by taking the square root more in depth.

For example:

If we are given the equation

we can first take the square root of both sides.

This will leave us with

Then subtract 5 from both sides and get

and

This leads us to a final answer of

If we had something more complicated like

then we would first have to get the by itself. So, first add 3 to both sides to isolate the . Now we are left with . Then take the square root of both sides

Subtract 2 from both sides

and

So
