Question 1128328

{{{sqrt(4x^2-4x+1 )= 2x - 1}}}



 {{{4}}} largest integer values of {{{2x-1}}} for which this equality is {{{not}}} true will be four integers  and they are:
{{{2x-1=0}}} 
{{{2x=1}}}
{{{x=1/2}}}......first solution for which  this equality  {{{is}}} true 

 {{{4}}} largest integer les than {{{x=1/2}}} are:

{{{x}}}={{{0}}},{{{-1}}},{{{-2}}},{{{-3}}}

the average of the {{{4}}} largest integer values:{{{(0+(-1)+(-2)+(-3))/4=-1.5}}}=>{{{-1}}}{{{1/2}}}


answer: A){{{-1}}}{{{ 1/2}}}
