Solve for x, given the equation Square root of x minus 5+ 7 = 11.
x = 21, solution is extraneous
x = 21, solution is not extraneous
x = 81, solution is extraneous
x = 81, solution is not extraneous

Best ResponseYou've already chosen the best response.5So it would be x=21 right?

Best ResponseYou've already chosen the best response.1what is an extraneous and nonextraneous solution means ?

Best ResponseYou've already chosen the best response.5Extraneous Solution is a solution of the simplified form of an equation that does not satisfy the original equation.

Best ResponseYou've already chosen the best response.1okay. substitute x for its value into the original equation if both sides are equal then 21 isn't extraneous solution if both sides aren't equal then 21 is an extraneous solution

Best ResponseYou've already chosen the best response.1\[\huge\rm \sqrt{x5}+7=11\] replace x with 21 solve left side

Best ResponseYou've already chosen the best response.1x=21 right now to check if it's an extraneous or nonextraneous you should substitute x for 21

Best ResponseYou've already chosen the best response.5I get a nonextraneous.

Best ResponseYou've already chosen the best response.1right \[\sqrt{215}+7=11\] both sides are equal so it would be nonex
