Analysis of errors in learning techniques

This page shows the results of analysis of error distribution throughout learning techniques used in four performed tasks. You see the total number of errors per particular technique. Observe that the main errors stem from inability to relate objectives and solution steps; accordingly, the recommended exercise aims at the development of this ability.

Solve the equation

{(- 40 y^{2} + 26 y - 3)}^{2} + {(20 y^{2} - 13 y + 6)}^{2} = {(- 20 y^{2} + 13 y - 2)}^{2} + 2 \cdot (20 y^{2} - 13 y + 6) \cdot (- 40 y^{2} + 26 y - 3)

Solve the problem with the following technique(s)
