whenever there is a radical in equation...square both sides

OpenStudy (erinweeks):

so it would be 7 ? but i dont get the extraneous solution .

OpenStudy (lgbasallote):

what do you get after squaring?

"extraneous" solution means it doesn't work in original equation 7 = sqrt(49) .....check 0 = sqrt(0) .... check there are no extraneous solutions
