Re-Test Policy (Heritage HS-wide policy): Students may be re-assessed on any and all tests throughout an academic quarter. The re-assessment may not be in the same form as the original test. The highest grade you can earn on a retest is a 90%. In order to qualify for a re-assessment, each student must… Have every homework assignment for the given unit completed by the re-test date. Complete the re-test on the date chosen by the teacher (within a week of having the test returned to the student). Remediate with the teacher on the material prior to the re-test.

Quiz Replacement Policy (Math Dept. policy): It is the philosophy here at Heritage HS that assessments are given in an attempt to see where each student is at in their learning, and make adjustments to further their education. Therefore, if a student performs better on a unit test than they did on a quiz within this unit, they may replace their lowest quiz grade with the better unit test grade. Only original test scores may replace quiz scores, not re-test scores.

Factoring trinomials “Bustin up the B”

Factor: ax2 + bx + c where a ≠ 1 (Busting the B!!) 4x2 + 7x + 3 Multiply a by c (12). What numbers have a product of 12 but a sum of b(+7)? 4 and 3 Substitute +7x with the above and use factor by grouping to factor. 4x2 + 4x + 3x + 3 continued next slide

4x2 + 4x + 3x + 3 (factor by grouping) Check your answer by using FOIL/distribute.

When leading coefficient is not one “Bustin up the B” 1. 2. 3. 4.

Factoring trinomials into the product of two binomials when leading coefficient is one. 1. 2. 3. 4. 5.
