First, we move  across the equals sign by multiplying both sides by  :

And then all we need to do is multiply both sides by :

First, we can move over across by multiplying both sides by it:

We can’t move the numerator over, so we next have to move the  back by multiplying both sides by its reciprocal :

Now we can move  across the equals sign by multiplying both sides by its reciprocal  :

And we can move   back over by multiplying by both sides by it:

And finally, we can move  across by dividing both sides by it: 

First, we can move the F by dividing both sides by it:

Now we can move  by multiplying both sides by it:

And finally, move the b by dividing both sides by it:

Start by moving  by multiplying both sides by its reciprocal  :

Now we can move  by multiplying both sides by it:

Finally, we can move the  across by multiplying both sides by its reciprocal . Any number with 1 as the denominator has the same value as the numerator, so we multiply the right-hand side by 2:

First, we can move  across the equals sign by multiplying both sides by its reciprocal :

Next, we move  across by multiplying both sides by it:

Finally, we take the square root of both sides to isolate C:
