Answer: No. Collin was wrong.
Step-by-step explanation:
From the question, we are informed that the answer that Collin had on his paper was β13 β (15 + 58) and the correct answer, located in the back of the book, was β13 β15 + 58.
Collin is wrong because he didn't take into cognisance the effect of minus on the bracket. Here, β13 β (15 + 58) will be equal to -13 -15 -18. This is because minus multiplied by plus equals to minus. He shouldn't have put the numbers in the bracket.
