Answer:
![\dfrac{x^2-4}{x^2-6x+9}](https://tex.z-dn.net/?f=%5Cdfrac%7Bx%5E2-4%7D%7Bx%5E2-6x%2B9%7D)
Step-by-step explanation:
We assume you want to expand ...
![\dfrac{x+2}{x-3}\cdot\dfrac{x-2}{x-3}=\dfrac{(x+2)(x-2)}{(x-3)^2}=\boxed{\dfrac{x^2-4}{x^2-6x+9}}](https://tex.z-dn.net/?f=%5Cdfrac%7Bx%2B2%7D%7Bx-3%7D%5Ccdot%5Cdfrac%7Bx-2%7D%7Bx-3%7D%3D%5Cdfrac%7B%28x%2B2%29%28x-2%29%7D%7B%28x-3%29%5E2%7D%3D%5Cboxed%7B%5Cdfrac%7Bx%5E2-4%7D%7Bx%5E2-6x%2B9%7D%7D)
_____
In each case, the product of the factors is ...
(x +a)(x +b) = x² +(a+b)x +ab
For the numerator, you have (a, b) = (2, -2).
For the denominator, you have (a, b) = (-3, -3).
I’m not sure about the estimates but the overall answers should be correct
