Solving Radical Equation

Solving Radical Equation

Let’s start with a simple equation

step 2) is to solve for “x”Example 1

heres how to check plug in the x value

Example 2

Try this one! Example 3

For this one move the 3 on the other side first to isolate radicals on one side.
Hint* don’t over complicate the problem

example 4

Now try this one

follow the same procedure
step 1) is to get rid of the square roots, to do that you must square both side of the equation
to avoid confusion On a separate sheet of paper solve the first side of equation.




After doing this plug this in the equation

Now move everything on the other side to isolate the radicals on one side of the equation


Now square the equation again to get rid of the radicals

Solve for “x”

YES! FINALLY DONE! woot woot!! sorry if i took me forever to do this i had work so yea anyways for the next scribber i pick hmmmm (look at the list) THANG N. since ur the first one on the list ur the next scribber =D if theres any mistakes please point them out thanks=D...haha well i better get some sleep hahah it sooo late, night everyone!
