The activity practices solving quadratic equations with real (rational and irrational) and complex roots. There are included quadratics in standard and vertex form, though more of the equations have terms on both sides. Students will need to
- simplify algebraic expressions
- use the formula for the product of the sum and difference of the same two terms
They are asked to solve the equations by the most appropriate method.
Activity Directions: Students solve 12 quadratic equations. They use a given table to find which character (letter, number or sign) corresponds to each of their answers and fill in another table to obtain a funny password. Students tell the password to the teacher. If it is correct, then they have solved all equations right.
Answer keys are included.
