I work through four examples of solving equations involving radicals. At minute 14:33 I dropped the negative sign when I copied my check...so my check was incorrect:( The 3rd example has no solution because -2 does not equal 2.
Examples start at 1:36 4:48 10:13 14:52 Find free review test, useful notes and more at http://www.mathplane.com
