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
