Answer from Gauth math
Step-by-step explanation:
When studying sets of numbers students have certain misconception
1) the correct of writing the tabular notation form
2) the differentiation between sets ( example certain sets have zero and certain do not have a zero - example 2 all integers are rational numbers but all rational numbers are not integers)
3) types (kinds ) of sets . ( onto - into and binary relation)
4) Domain and Range of sets
Option C:
is the product of the rational expression.
Explanation:
The given rational expression is ![\frac{x+3}{x+2} \cdot \frac{x-3}{x-2}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%2B3%7D%7Bx%2B2%7D%20%5Ccdot%20%5Cfrac%7Bx-3%7D%7Bx-2%7D)
We need to determine the product of the rational expression.
<u>Product of the rational expression:</u>
Let us multiply the rational expression to determine the product of the rational expression.
Thus, we have;
![\frac{(x+3)(x-3)}{(x+2)(x-2)}](https://tex.z-dn.net/?f=%5Cfrac%7B%28x%2B3%29%28x-3%29%7D%7B%28x%2B2%29%28x-2%29%7D)
Let us use the identity
in the above expression.
Thus, we get;
![\frac{x^{2} -3^2}{x^{2} -2^2}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B2%7D%20-3%5E2%7D%7Bx%5E%7B2%7D%20-2%5E2%7D)
Simplifying the terms, we get;
![\frac{x^{2}-9}{x^{2}-4}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B2%7D-9%7D%7Bx%5E%7B2%7D-4%7D)
Thus, the product of the rational expression is ![\frac{x^{2}-9}{x^{2}-4}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B2%7D-9%7D%7Bx%5E%7B2%7D-4%7D)
Hence, Option C is the correct answer.
