Outcomes

12CT.B.3.1

Solve polynomial equations in one variable, of degree no higher than four (e.g., x^2 – 4x = 0, x^4 – 16 = 0, 3x^2 + 5x + 2 = 0), by selecting and applying strategies (i.e., common factoring; difference of squares; trinomial factoring), and verify solutions using technology

12CT.B.3.2

Solve problems algebraically that involve polynomial functions and equations of degree no higher than four, including those arising from real-world applications
