Răspuns :
||x-5|-2|=3
|x-5|-2=+-3
|x-5|-2=-3. ............. sau.........…..|x-5|-2=3
|x-5|=-3+2.....................................|x-5|=3+2
|x-5|= - 1...........................................|x-5|=5
x1= mulțimea vidă
|x-5|=5
x-5=+-5
x-5=-5 ..............sau.........x-5=5
x2=-5+5...............sau .......x3=5+5
x2=0 ....................sau .......x3=10
x={0;10}
S={0;10}
||x-5|-2|=3
||x-5|-2|= -3
||x-5|-2|=3
|x-5|= 3+2
x-5=5 => x = 10
x-5= -5 => 0
||x-5|-2|= -3
|x-5|= -3+2
|x-5|=-1 = nu se poate =>
x ∈ ∅
☕︎︎ Ecuația are 2 soluții:
x¹=0
x²=10
S={0;10}
