  1. MATH 2201 CHAPTER 7 - QUADRATIC EQUATIONS Review and Introduction

  2. Learning Goals for Chapter 7 You will develop your algebraic and graphical reasoning. You will be able to solve quadratic equations by… • graphing (Section 7.1) • factoring (Section 7.2) • using the quadratic formula (Section 7.3)

  3. Review We are use to solving for 1 variable with a degree of 1.In Math 1201 we solved the linear equation: y = mx + b

  4. Review We know how to solve for 1 variable with a degree of 2. Earlier this year we learned about radials and how to solve for x when x has a degree of 2 (or higher).

  5. Try Solving…

  6. What About…

  7. Quadratic Equation Quadratic Equation: a polynomial equation of the second degree The standard form of a quadratic equation is…

  8. Note! A lot of students have trouble with x² Try the following: Solve for y when x = 2 y = 4x² Solve for y when x = 2 y = (4x)² VS
