Notes: Solutions may include simplifying radicals or writing solutions in simplest radical form. An example for inspection would be x² = 49, where a student should know that the solutions would include 7 and −7. When utilizing the quadratic formula, there are no coefficient limits. The discriminant is a sufficient way to recognize when the process yields no real solutions.

Standards derived from the same national standard

Solve quadratic equations by inspection (e.g., for 𝑥² = 49), taking square roots, factoring, completing the square, and the quadratic formula, as appropriate to the initial form of the equation (limit to real number solutions).
