Evidence Statement Key: A-REI.4a-1
Calculator: X
Y = Yes; Assessed on Calculator Section
X = Calculator is Specific to Item
N = No; Assessed on Non-Calculator Sections
Z = Calculator Neutral (Could be Calculator or Non-Calculator Sections)
Point: 1 each (1:26)
Evidence Statement Text:
Solve quadratic equations in one variable. a) Use the method of completing the square to transform any quadratic equation in x into an equation of the form (x - p)2 = q that has the same solutions.
Clarifications, limits, emphases, and other information intended to ensure appropriate variety in tasks:
1. The derivation part of the standard is not assessed here; it is assessed under Subclaim C.
