This week in Pre- Cal we went over Radical Equations and how to solve the equation. When solving a radical equation you need to move the variable to either the  left or right side of the = sign trying to isolate the variable. Also when solving a radical equation, when you have square root you would square it to get ride of the radical, make sure what you do to one side of the equations you do to the other and you would be left with the side without the radical and the other side would be squared.

Example:  make sure you are always checking that the variable would work if you put it back into the equation

I did learn this week that when Simplifying a Quotient of Radical Expression. You never want a radical in the denominator when you have an expression.

Step 1 : Multiply the numerator and the denominator by the radical in the denominator

Step 2: Then conjugate of the binomial denominator

Step 3: value the variable

Example:
