Factorize the following polynomial completely, giving your answer as a product of its linear factors. $x^4 - 29x^2 + 100$

Figure 1 shows the steps in a student's solution for the equation $\log_2(5x+1) - \log_2(x-4) = 2$. The student made an error in the working which resulted in an incorrect solution.

Figure 1. Worked solution to a logarithmic equation

Identify the step in which the student made the initial error and correctly rework the solution from that step.
