Solving quadratic equations by completing the square: Applying Newman’s Error Analysis Model to analyse Grade 11 errors

Pythagoras, 2023
Error analysis is an instructional strategy that can assist teachers to identify learners’ areas of weakness in mathematics and that can point to remediation of those errors.

Quadratic Diophantine equations in the rational and quadratic fields [PDF]

Transactions of the American Mathematical Society, 1942
with integral coefficients from the field of rational numbers or from some quadratic field. The quantity A is defined for convenient reference. We can take ap, O without any loss of generality, by the use (if necessary) of linear transformations of determinant unity (so that the number of integral solutions is not changed).

Linear Hamiltonian behaviors and bilinear differential forms [PDF]

, 2004
We study linear Hamiltonian systems using bilinear and quadratic differential forms. Such a representation-free approach allows us to use the same concepts and techniques to deal with systems isolated from their environment and with systems subject to ...

A General Uniqueness Theorem concerning the Stability of Additive and Quadratic Functional Equations

Journal of Function Spaces, 2015
We prove a general uniqueness theorem that can be easily applied to the (generalized) Hyers-Ulam stability of the Cauchy additive functional equation, the quadratic functional equation, and the quadratic-additive type functional equations.

Stage‐Dependent β‐Synuclein Links MRI and Cognitive Decline in Alzheimer's Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Synaptic degeneration drives cognitive decline in Alzheimer's disease (AD), but synaptic biomarkers are scarce. Brain‐enriched β‐synuclein emerged as a synaptic damage marker. We investigated its diagnostic, prognostic, and structural correlates across the AD continuum.

Discordance Between Systemic Lupus Erythematosus Disease Activity Index Domain Weights and Their Association With Organ Damage Accrual

Arthritis Care &Research, EarlyView.
Objective Studies of damage accrual in patients with systemic lupus erythematosus (SLE) show associations with disease activity measured by the SLE Disease Activity Index 2000 (SLEDAI‐2K), but these associations are imperfect. SLEDAI scores are powerfully influenced by weightings (1–8) assigned to each domain.
