Lyrics

[Verse 1]
When polynomials hide their secrets deep
Four operations dance but roots still weep
Addition, subtraction, multiply, divide
Plus radical extraction as our guide
Galois whispered truths we need to know
The group that guards determines if roots show

[Chorus]
Solvable by radicals, the ancient quest
When Galois groups are tame, we find the rest
Normal subgroups stacking like a tower tall
Each quotient must be abelian through it all
S-one through S-four unlock every door
But S-five breaks the pattern, blocks us from more

[Verse 2]
Symmetric groups hold polynomials' fate
Four degrees submit, but five won't capitulate
A chain of normal subgroups must unfold
Where every factor's commutative and controlled
But alternating five stands proud and simple
No normal subgroups pierce its perfect dimple

[Chorus]
Solvable by radicals, the ancient quest
When Galois groups are tame, we find the rest
Normal subgroups stacking like a tower tall
Each quotient must be abelian through it all
S-one through S-four unlock every door
But S-five breaks the pattern, blocks us from more

[Bridge]
It's not that we lack cleverness or skill
The quintic's symmetry defies our will
A-five lives inside S-five's heart
Simple and non-abelian, tears hope apart
Structure blocks extraction, not our minds
The group itself determines what math finds

[Outro]
Radical solutions bow to group control
Galois showed us symmetry's true role
When groups unravel nice and neat
Polynomials surrender at our feet
But complex symmetries guard their treasure tight
Some equations stay beyond our radical sight
