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).

All Valves Closed. This phase of the cardiac cycle begins with the appearance of the QRS complex of the ECG, which represents ventricular depolarization. This triggers excitation-contraction coupling, myocyte contraction and a rapid increase in intraventricular pressure. Early in this phase, the rate of pressure development becomes maximal.
