Quality Control Verification in Solar Grid Modeling
Review the technician's process and explain how they can correct their error to fully factor the expression. In your response, address the following based on the standard rules of factoring by grouping:
- State what factor the technician should have factored out of the second group, -4x + 2, in Step 3 so that the binomial factor matches the first group.
- Write the resulting intermediate expression after factoring the GCFs from both pairs.
- State the final factored form of the expression.
- Briefly explain how to check if the final factored form is correct.
