Unformatted text preview: x terms cancel to leave, 9 2 2 1 2 1 2 2 2 = + + + x n n ( ) ( ) . Finally, this can be solved for x to give, x n n =+ + [ ( ) ] ( ) 9 2 1 2 2 1 2 . Examination of this equation shows that x gets smaller as n gets larger, so to find the largest x , we should use the smallest n . Therefore, choose n = 0, and the equation for x becomes, x = (9 ) . Then, x = 8.75...
