    why wouldn't it be x = 5, not extraneous ?

    I had just gone straight to squaring the whole equation?

    5 is under the square root so you can't move it to the right without removing square root

    well well well. first step is to divide both side by 2

    then take square root both sides

    cause of the two infront of the radical?

    yep right you need to transfer all numbers that is outside the radical sign to the right side that's always going to be First step

    to take square root you need just radical sign at left side
