The error was done in Step C, because the student omitted the of the algebraic identity . Step C must be

Step-by-step explanation:

First image attached

The error was done in Step E, because student did not multiply by the negative sign in numerator. The real numerator in Step E should be:

Hence, Step E must be .

Second image attached

The error was done in Step C, because the student omitted the of the algebraic identity . Step C must be

And further steps are described below:

Step D

Which according to the Quadratic Formula, represents a polynomial with complex roots. That is: (, , )

(Conjugated complex roots)

Step E

Step F

step-by-step explanation:

the central idea is that:

individuals should refuse to cooperate with institutions they believe unjust.

thoreau felt  that governments were more often agents of corruption than justice, even democracies, and that just because the majority feels a certain way does not make it just or correct in absolute terms. he uses the fact that slavery exists in our democracy to support this idea.
