The equation you solved is NOT the equation shown in the flash screen of the video listing on UA-cam. Just square both sides of the equation to start !
Way too longwinded! Can be solved in 4 steps: Step 1 Devide both sides by 2 Step 2 Replace x in numerator by sqrt(x)×sqrt(x) Step 3 Shorten fraction of left side Step 4 Square both sides. Result x=4 p.s. x cannot be 0 as it is in the denominator. x cannot be negative as right side is positive.

L' equazione del titolo è diversa ed ha come soluzione 1/4 .
The equation in the title is not the equation you solve. For Olympiad mathematics I find it extremely simple.
Way too longwinded!
Can be solved in 4 steps:
Step 1
Devide both sides by 2
Step 2
Replace x in numerator by sqrt(x)×sqrt(x)
Step 3
Shorten fraction of left side
Step 4
Square both sides.
Result
x=4
p.s.
x cannot be 0 as it is in the denominator.
x cannot be negative as right side is positive.
0/0 =/= 0!
