Caleb **first made a mistake in step 1**.
In Step 1, he should have distributed the negative sign to both terms inside the second parentheses, which would modify -3.6k into -3.6k and +5.1k² into -5.1k². Correctly, it should read:
\[
−4.6k^2 + 2.5k - 3.8 - 3.6k - 5.1k^2
\]
This means Caleb made a mistake initially, which carries through to the subsequent steps.
