Simplify the following term
`{(x-1/x)*(x+1/x)*(x^2-1/x^2)}` is

Find the sum to n terms of the following series: (x+(1)/(x))^(2)+(x^(2)+(1)/(x^(2)))^(2)+(x^(3)+(1)/(x^(3)))^(2)+(x^(4)+(1)/(x^(4)))^(2)+

Simplify each of the following x(x + 4) + 3x (2x^(2) - 1) + 4x^(2) + 4

Simplify each of the following 3x^(2) + 2(x + 2) - 3x (2x + 1)

Simplify each of the following 2x^(2) + 3x (1 -2x^(3)) + x(x + 1)

Express the following in the lowest terms. ((2x^(2)+1)/(x-1)+(x-1)/(x+1))xx((x^(2)-1)/(2x)):
