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).

Phonation. The process of speech production by the human voice may be divided into phonation, resonation, and articulation. Phonation is the process by which energy from the lungs in the form of air pressure is converted into audible vibrations.One method of phonation involves using the air pressure to set the elastic vocal folds into vibration, a process called voicing.honation is the process by which energy from the lungs in the form of air pressure is converted into audible vibrations.
