EQUATIONS CONTAINING VARIABLES UNDER ONE OR MORE RADICALS

Note:




Example 1:

tex2html_wrap_inline91



First make a note of the fact that you cannot take the square root of a negative number. Therefore, tex2html_wrap_inline93 or tex2html_wrap_inline95.




Square both sides of the equation.

Add 8 to both sides of the equation.

displaymath87

The answer is x=17.



Check the solution by substituting 17 in the original equation for x. If the left side of the equation equals the right side of the equation after the substitution, you have found the correct answer.
