English short note.
Report speech.
Reporting speech, also known as indirect speech or reported speech, is a way of conveying someone else's words or ideas without using their exact words. It is a method of relaying what someone said or thought using our own words.
When using reported speech, we typically change the tenses, pronouns, and certain expressions to convey the original speaker's message accurately.
✅Example 1:
Direct Speech: John said, "I am going to the movies tonight."
Reported Speech: John said that he was going to the movies that night.
✅Example 2:
Direct Speech: Sarah asked, "Can you lend me your book?"
Reported Speech: Sarah asked if I could lend her my book.
✅Example 3:
Direct Speech: Peter shouted, "I'll be late for dinner!"
Reported Speech: Peter shouted that he would be late for dinner.
✅Example 4:
Direct Speech: Lisa exclaimed, "What a beautiful view!"
Reported Speech: Lisa exclaimed how beautiful the view was.

Answer for this question:
Adding 2xy to both sides of the equation x² + y² = xy yields x² + y²+ 2xy= 3xy.
x² + y² + 2xy = (x+y)² = 3xy.
Then we have been asked (x+y)⁴?
so (x+y)⁴ = ((x+y)²)².
(x+y)⁴ = (3xy)² because (x+y)² = 3xy.
Thus, (x+y)⁴ = 9x²y².
