This week in pre – calc 11 we learned chapter 2.6 – solving equations algebraically. One thing that stood out to me was learning how to rationalize the denominator to solve an equation that looks like this one:
The first step is to multiply the “rationalize” it. The multiplies with everything and cancels out the on the bottom of the equation.
The next step would be to further simplify but as we can see we no longer can simply this equation further, so we leave it like this
Here is an example of an equation which also requires to be rationialized, take a couple seconds and try to solve this using what you know about rationalization:
Below is the answer and me solving this equation using rationalization:
