放ほうっておく
More neutral and common; ほっぽらかす is more casual and carries a stronger nuance of irresponsibility or neglect.
放ほう置ちする
Formal, often used for leaving things unattended; ほっぽらかす is colloquial and emotionally charged.

Likely derived from 放る (ほる, 'to throw away') with an emphatic or colloquial suffix; the exact derivation is uncertain.
