The difference of the fractions as given in the task content is; (4-2x) / (x²-16).
According to the task content, the fractions whose difference is to be evaluated are as indicated below;
[tex] \frac{x}{( {x}^{2 } - 16)} - \frac{3}{x - 4} [/tex]
Hence, the LCM of the denominators of both fractions can be evaluated as;
x -3(x+4)/(x²-16).
(4-2x) / (x²-16)
Hence, the difference of the two fractions is; (4-2x) / (x²-16).
