(x+1/x-1 - x-1/x+1 - 4x/x^2 +1) + 4x/x^4-1​
Lunna [17]

Answer:

\frac{12x}{x^4-1}

Explanation:

Given

(\frac{x+1}{x-1} - \frac{x-1}{x+1} - \frac{4x}{x^2 + 1}) + \frac{4x}{x^4 - 1}

Required

Solve:

Take L.C.M of the first two fractions

(\frac{(x+1)(x+1)-(x-1)(x-1)}{(x-1)(x+1)} - \frac{4x}{x^2 + 1}) + \frac{4x}{x^4 - 1}

(\frac{(x+1)(x+1)-(x-1)(x-1)}{x^2-1} - \frac{4x}{x^2 + 1}) + \frac{4x}{x^4 - 1}

(\frac{x^2+2x+1-(x^2-2x+1)}{x^2-1} - \frac{4x}{x^2 + 1}) + \frac{4x}{x^4 - 1}

(\frac{x^2+2x+1-x^2+2x-1}{x^2-1} - \frac{4x}{x^2 + 1}) + \frac{4x}{x^4 - 1}

Collect Like Terms

(\frac{x^2-x^2+2x+2x+1-1}{x^2-1} - \frac{4x}{x^2 + 1}) + \frac{4x}{x^4 - 1}

(\frac{4x}{x^2-1} - \frac{4x}{x^2 + 1}) + \frac{4x}{x^4 - 1}

Solve the expression in bracket

(\frac{4x(x^2+1) - 4x(x^2-1)}{(x^2-1)(x^2+1)} ) + \frac{4x}{x^4 - 1}

(\frac{4x(x^2+1) - 4x(x^2-1)}{x^4-1} ) + \frac{4x}{x^4 - 1}

(\frac{4x^3+4x - 4x^3+4x)}{x^4-1} ) + \frac{4x}{x^4 - 1}

(\frac{4x^3- 4x^3+4x +4x)}{x^4-1} ) + \frac{4x}{x^4 - 1}

\frac{8x}{x^4-1} + \frac{4x}{x^4 - 1}

Take LCM

\frac{8x+4x}{x^4-1}

\frac{12x}{x^4-1}

<em>The expression can not be further simplified</em>

natka813 [3]

Some species of plants and animals flourished in both areas, and some did not. There were many new animals and plants in the Americas that Europeans had never seen. And, Europeans brought plants and animals to the New World that America had never seen. The Colombian Exchange was also a cultural exchange. New agricultural developments were traded, economic activity and opportunities opened up between the New and Old Worlds, and new ideas were exchanged. The ability to grow corn and potatoes. These two starchy foods, high in nutrients kept many Europeans from starving. Some of the things that Native Americans received as a result ofthe Columbian Exchange are as follows: . Horses . Firearms (beginning with muskets) . Textiles to use for clothing and ornamentation (although manySouth American Indigenous Peoples, such as the "Inca," already wereweaving their own textiles at least a century before the arrival ofthe Europeans).
