The last term in the trinomial does not have any variables, so we do not need to carry any variables into the parentheses as a result. Handling Coefficients. Now identify the coefficient of the first and last terms in the original set of parentheses, s 2 - 5s + 6. The coefficients are 1 and 6.
A premature ventricular contraction ( PVC ) â also known as a premature ventricular complex , ventricular premature contraction ( or complex or complexes ) ( VPC ) , ventricular premature beat ( VPB ) , or ventricular extrasystole ( VES ) â is a relatively common event where the heartbeat is initiated by Purkinje fibers in the ventricles rather than ...
