Выражение: (x+5)^2+(x-10)^2=2*x^2
Решаем по действиям:
1. (x+5)^2=x^2+10*x+25
2. (x-10)^2=x^2-20*x+100
3. x^2+x^2=2*x^2
4. 10*x-20*x=-10*x
5. 25+100=125
6. 2*x^2-2*x^2=0
-------------->
x^2+10*x+25+(x-10)^2-2*x^2=0
2*x^2+10*x+25-20*x+100-2*x^2=0
2*x^2-10*x+125-2*x^2=0
2*x^2-10*x+125-2*x^2=0
-10*x+125=0
Решаем относительно x:
x=-(-125)/10=125/10=25/2~~12.5.
