Unformatted text preview: x 26 x = ( x3) 29 . Likewise, 2 y 2 + 4 y = . . . z 22 z = . . . y 2 + 4 y = ( y + 2) 24 z 22 z = ( z1) 21, so x 2 + y 2 + z 26 x + 4 y2 z = ( x3) 29 + ( y + 2) 24 + ( z1) 21 = 11 , or ( x3) 2 + ( y + 2) 2 + ( z1) 2 = 11 + 9 + 4 + 1 = 5 2 . conclusion: center = (3, 2, 1), radius = 5....
