Either A or C equals zero, but not both. After creating a rule, students test their rule with other examples. Algebra and geometry. The student knows the relationship between the geometric and algebraic descriptions of conic sections. Clarifying Activity For a simple situation, students model the process of completing the square.
Students first model the process using algebra blocks.
4x Students use blocks to form a square. To complete the square add 4 units. Clarifying Activity Students use the method of completing the square to translate equations into standard form in order to sketch the conic.
