When solving quadratic equations in general, first get everything over onto one side of the "equals" sign (something that was already done in the above examples). Then first check to see if there is an obvious factoring or if there is an obvious square-rooting that you can do. If not, then it's usually best to resort to the Quadratic Formula.

Have students build models of the reactants and products, using the gumdrops and toothpicks for each equation. The gumdrops represent the atoms, and the toothpicks, the bonds. For the purpose of this balancing exercise, it is not important that students model correct bond angles; numbers and types of atoms are the important things. The LogEC 50 between naïve and CORT treatment did not differ (F 1,70 = 0.0070, P = 0.93), but there was a significantly larger current in CORT‐treated slices in response to the highest concentration of muscimol (P = 0.027 vs. naïve). These data indicate that CORT incubation does not affect the potency of muscimol but it does increase efficacy.
