This lesson extends the factoring concepts and techniques covered in Topic B of this module to the complex numbers and specifically addresses N-CN.C.7. Students will learn how to solve and express the solutions to any quadratic equation.
Students observe that complex solutions to polynomial equations with real coefficients occur in conjugate pairs and that only real solutions to polynomial equations are also the 𝑥-intercepts of the graph of the related polynomial function. In essence, this is the transition lesson to the next lesson on factoring all polynomials into linear factors.
