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).

venÂ·tricÂ·uÂ·lar phoÂ·naÂ·tion. Voice produced by vibration of the ventricular (vestibular) folds, just above the vocal folds. This may occur as a substitute for, or in addition to, vocal fold vibration, and creates a hoarse, low-pitched voice.Synonym(s): vestibular phonation.enÂ·tricÂ·uÂ·lar phoÂ·naÂ·tion.
