# MAFS.912.N-CN.3.7

Solve quadratic equations with real coefficients that have complex solutions.
General Information
Subject Area: Mathematics
Domain-Subdomain: Number & Quantity: The Complex Number System
Cluster: Level 1: Recall
Cluster: Use complex numbers in polynomial identities and equations. (Algebra 2 - Additional Cluster) -

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.

Date of Last Rating: 02/14
