[Task 1] Substitution: Can you tell What's Wrong?

Indicate your responses under comments:
(i) Identify the error(s) and describe what's wrong.
(ii) What is the correct answer?

Post-Lessson elaboration

As discussed in the lesson, the errors in the above working:

• Line 1: Error in first 2 terms - Should not be (2 x 3)^2; similarly, should not be (3 x 2)^2
• Line 1: While the substitution of the 3rd term is correct, should insert () for "-1". This applies to how "-1" was written in lines 2 & 3.

The suggested worked solution:
