$x neq 0,$ поскольку x есть в знаменателе данного уравнения.
Ну а далее:
$1+ sqrt{2x+1}=x \ sqrt{2x+1}=x-1 \ 2x+1= (x-1)^{2} \ 2x+1= x^{2} -2x+1 \ x^{2} -4x=0\x(x-4)=0 \ x_{1}=0 \ x_{2}=4 \$
x=0 не удовлетворяет условию данного задания.
Ответ: $x=4$

...Ну и как "Лучший ответ" не забудь отметить, ОК?!.. ;)

Что-то ты намудрил. x^2-4x откуда появилось - это раз, а во-вторых от x в самом начале надо было избавиться умножением двух частей уравнения на x

Поспешил ты отметить как нарушение, это глюк редактора. Я как раз исправлял, и не успел...

Это и сделано в самой первой строчке (умножение на х), но х не должен быть равен нулю.
