What is the common denominator of 5/x2-4,-2/x+2

Answer: A) (x + 2) (x - 2)

Step-by-step explanation:

The given complex fraction is

Thus we can see that the common denominator in the above complex fraction is A) (x + 2) (x - 2)

complete question:

What is the common denominator of 5/x²-4,-2/x+2

Answer:

The common denominator are (x + 2) and (x - 2).

Step-by-step explanation:

The expression is 5 / x2-4 and - 2/x+2 . The numerator is the value above the back slashed signs. The numerator in the first expression 5 / x2-4 is 5 while the numerator for the second - 2/x + 2 is - 2.

The denominator is the value below which is x² - 4 and x + 2. To get the common denominator for the first one, you need to expand the value.

x² - 4

-2 and + 2 when added together will give you 0 and also if you multiply the two value - 2 and + 2 together you will get - 4

so x² - 4 can be expanded as

(x + 2) (x - 2).

Therefore the common denominator are (x + 2) and (x - 2).
