Question

Perform the indicated operations.

a^2-4 ,,,,,,,,a^2-2a ,,,,,,,,2-y

--------- ÷ ------------- + ---------

x^2-9 ,,,,,,,,, xy+3y,,,,,,,,, x-3


PS. (------ is to show a fraction)


Awnser = [ ] IF X does not equal something

Answer 1

Answer: (a^2 - 4)/(x^2 - 9) + (a^2 - 2a + (2-y))/(xy + 3y) - (x-3)

Step-by-step explanation: First, you need to simplify the fraction in the first term:

(a^2 - 4)/(x^2 - 9)

Next, you simplify the fraction in the second term:

(a^2 - 2a + (2-y))/(xy + 3y)

Then you subtract (x-3) from the fractions obtained in step 1 and 2:

(a^2 - 4)/(x^2 - 9) + (a^2 - 2a + (2-y))/(xy + 3y) - (x-3)

This is the final result of the operation.

It is important to note that the answer is a simplified fraction and only valid if x does not equal 3. If x=3, the denominator x-3 would be equal to zero, which is not allowed in mathematics.
