EQUATIONS CONTAINING VARIABLES UNDER ONE OR MORE RADICALS



Note::

Check the solution by substituting tex2html_wrap_inline137 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.

Left side:

tex2html_wrap_inline141

tex2html_wrap_inline143

Right side: Since the left side of the original equation equals the right side of the

original equation when you substitute tex2html_wrap_inline137 , the answer is correct.

You can also check the answer by graphing

tex2html_wrap_inline147

(the left side of the original equation minus the right side of the

original equation). The solution will be the x-intercept. The x-intercept

is tex2html_wrap_inline149
