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).

ventricle. The patient is phonating, and the air bubblingthrough the anesthetic agent prevents visualization of a distinct air-fluidlevel in the larynx. The laryngeal ventricle and lower portion of the vestibule (arrow) is largely submerged in anesthetic agent and poorly outlined.
