Apply the fraction rule
$\frac{a}{c}-\frac{b}{c}=\frac{a-b}{c}$
$=\frac{x(x-1)-3(x+1)}{(x+1)(x-1)^{2}}$
Simplify
$x(x-1)-3(x+1):{\quad}x^{2}-4x-3$
$=\frac{x^{2}-4x-3}{(x+1)(x-1)^{2}}$

Equine infectious anemia (EIA) is considered the main infectious disease in Brazilian equine farming, for which there is no effective vaccine or treatment. It is caused by a retrovirus of the genus Lentivirus, which affects horses, donkeys and mules and is transmitted in nature mainly by hematophagous insects of the genus Tabanidae. Researchers analyzed the records of 9,439 equids from Acre, submitted to the agar gel immunodiffusion test (AGID) for equine infectious anemia (EIA), between 1986 and 1996. Of these, 6199 tested positive for equine infectious anemia (EIA) . Knowing that the age of AIE-positive horses follows a Normal distribution with a mean of 5 years and a standard deviation of 1.5 years, determine the expected number of AIE-positive horses in the Acre sample that will be aged less than or equal to 3 years. ATTENTION: Provide the answer to exactly FOUR decimal places.
