To solve this fraction we have to reduce to the same denominator, but prior to reducing, note that one of the denominators x²-4 could be expanded to:
(x-2)(x+2)   [remember a² - b² =n(a-b)(a+c)]

Let the denominator be (x-2)(x+2),

2/(x-2)(x+2) -(x-2)/(x-2)(x+2) = 3(x+2)/ (x-2)(x+2) ==>

2 -(x-2) = 3x+6 ==>2-x+2 = 3x+6 ==> x=-4/6 ==> x= - (1/2)

TiliK225 [7]

Answer:

26

Step-by-step explanation:

1 batch is 1/4 cups of cranberries.

This means that we have to find the number of groups of 1/4 in  6 1/2 cups to find the number of batches.

(The decimal forms of these numbers are 6.5 and 0.25)

6.5/0.25=26

There are 26 batches
