Question

let's find what must be added or subtracted from 9p^2+ 1/9p^2 to make it a perfect square​

Answer 1

Answer:

we know that....

.... a²+b²=(a+b)² - 2ab

a²+b²=(a - b)² +2ab

• 9p²+1/9p²
• (3p)²+(1/3p)²
• (3p+1/3p)² - 2.3p.1/3p
• (3p+1/3p)² - 2

Or.....

• 9p²+1/9p²
• (3p)²+(1/3p)²
• (3p - 1/3p)² +2.3p.1/3p
• (3p - 1/3p)² +2

Answer 2

Answer:

9p^2 + 1/9p^2 +

9p^2/1 + 1/9p^2 + 2/1

then p & p will get cut out and 2 & 2 will get cut out

9 + 1/9 + 1

then 9 & 9 will get cut out

1 + 1

= 2

Same with -2

Ans = 2 or -2
