If `|2x – 1| < 3,` then `x` is

If A = (2x + 1)/(2x - 1) and B = (2x - 1)/(2x + 1) then A - B is equal to:

(x-1) / (2x + 1) + (2x + 1) / (x-1) = (5) / (2), x! =-(1) / (2), 1

2^|x+1| - 2^(x) = |2^(x)-1| + 1

If : cot theta = (2x(x+1))/(2x+1), "then" : cos theta = A) (2x + 1 )/(2x^(2) + 2x + 1 ) B) (2x )/(2x^(2) + 2x + 1 ) C) (2x(x+1) )/(2x^(2) + 2x + 1 ) D) (x+1)/(2x+1)

(2x + 1) / (x) + (4x) / (2x + 1) = 5

int (2x-1) / (2x ^ (2) + 2x + 1) dx

If 2 ^(x +1) + 2 ^( x-1)= 80, then find the value of x.

(2x + 1)(2x -1 ) = 3

Solve for x : (x - 1)/(2x + 1) + (2x + 1)/(x -1) = 2 , where x ne - (1)/(2) , 1
