√x^2-2011x+2010+x^2-2012x+2011=√1997x-x^2-1996

Question

√x^2-2011x+2010+x^2-2012x+2011=√1997x-x^2-1996

Answer 1

√x^2-2011x+2010+x^2-2012x+2011=√1997x-x^2-1996

x^2-2011x+2010+x^2-2012x+2011=1997x-x^2-1996 

3х²-6020х+6017=0

D=6020²-4*3*6017=36168196

√D=6014

x1=(6020-6014)/6=1

x2=(6020+6014)/6=12034/6=6017/3
