[UPDATE on 7 July] Solution received 

From Irina

• Very clear and systematic presentation of working. 👍
• Approach: Substitution is cleverly used to make the working easy to read and simplify 👍
• Answers are correct. 👍

[Point to ponder] Instead of using x = 6987650, what if we use x = 6987654? 

Try that to see how the expression would look like now.

[To improve] Use descriptive word like "Let x = 6987650" instead of using a straight line, which could be mistaken as "minus"

From Ruihao

• Very clear and systematic presentation of working. 👍
• In Ruihao's working, you would notice that he exercised his 'eye power' and notice he could applied special product to factorise part of the expression (in the course of simplifying the expression 👍
• Answers are correct 👍

[Updated 4 July] Proposed solution by Aravind 👍

• Method (approach) is clearly written... close to getting the correct answer
• [To mprove the clarity of the meaning making] Write out the given expression (px - q)(px + q) below the product of factors found to make the comparision.
