Unit 3: • Know the standard form, the terms that make it up, the coefficients and what they tell you about the shape and properties of the quadratic • Know the factored form and manipulate it geometrically and algebraically • Know the vertex form and manipulate it geometrically and algebraically • Important coordinates: • Find max/min of a quadratic • Find the equation of a quadratic given intercept and 2 points • Find the equation of a quadratic given vertex and 1 point. • Convert between different quadratic forms • Completing the square • Factoring • Solving quadratic equations • Zero factor principle • Quadratic formula • Know the discriminant and what it tells you about the number of solutions If discriminant is positive, you get 2 real solutions, if it is negative you get no real solutions and if it is 0, you get 1 solution. The review should be your starting point. Use the suggested HW problems for practice. The keys are posted in Husky Hub Topics.
