(x^2-16)/(x^4-16)<0

Solution

\frac{x ^{2} - 16}{x ^{4} - 16} < 0

Solution

- 4 < x < - 2 or 2 < x < 4

+1

Solution steps

\frac{x ^{2} - 16}{x ^{4} - 16} < 0

Factor

\frac{x ^{2} - 16}{x ^{4} - 16} : \frac{( x + 4 ) ( x - 4 )}{( x ^{2} + 4 ) ( x + 2 ) ( x - 2 )}

\frac{( x + 4 ) ( x - 4 )}{( x ^{2} + 4 ) ( x + 2 ) ( x - 2 )} < 0

Identify the intervals

- 4 < x < - 2 or 2 < x < 4
