The expression is a trinomial, like the expressions which we've been factoring in this lesson. There is a small variation in this problem however -- the first term has a coefficient that is not 1.
Ventricular Phonation (Plica Ventricularis). This occurs when a great amount of muscle tension above the vocal folds is created in the laryngeal area causing an approximation of the false vocal folds.entricular Phonation (Plica Ventricularis).

Premature ventricular contractions (PVCs) are extra, abnormal heartbeats that begin in one of your heart's two lower pumping chambers (ventricles).These extra beats disrupt your regular heart rhythm, sometimes causing you to feel a flip-flop or skipped beat in your chest.remature ventricular contractions (PVCs) are extra, abnormal heartbeats that begin in one of your heart's two lower pumping chambers (ventricles).
