Answer:
Given,
Now,
Use the algebraic identity ⇻ (a - b)² = a² - 2ab + b²
✐ So, the value of 9x² + 4y² - 1 is <u>24 + 12xy</u>
Now,
xy = - 2
So, 12xy = 12 × - 2 =<u> - 24</u>
•°• 24 + 12xy
= 24 + (-24)
= 24 - 24
= <u>0</u>
<h3>
⎆ The value of 9x² + 4y² - 1 is
<u>0</u>.</h3>

Step-by-step explanation:
so you have to write it all the way and then divide with the denominator then shift the numerator on the other side of the numerator
Answer:
let the other number be x
x+2=65
x=65-2
x=63
