`2x-1=x`

If (x^(3)+x^(2)+x+1)/(x^(3)-x^(2)+x-1)=(x^(2)+x+1)/(x^(2)-x+1), then the number of real value of x satisfying are

Show that (x^(3)+x^(2)+x+1)/(x^(3)-x^(2)+x-1)=(x^(2)+x+1)/(x^(2)-x+1) is not possible for any x varepsilon R.

(2x-1)/(2x+1)+(2x+1)/(2x-1)=6

simplify (2x-(1)/(2x))^(2)-(2x+(1)/(2x))(2x-(1)/(2x))

Solve for x: 2(x^(2) -1) = x( 1-x)

Lt_(x to (1)/(2))((x)/(2x-1)-(2x)/(4x^(2)-1))=

Prove that (2^(x-1)+2^(x))/(2^(x+1)-2^(x))=(3)/(2)

Prove that : ( 2^(x-1) + 2^x ) / ( 2^( x+1 ) - 2^x ) = 3/2

Find all the x -intercepts of f(x)=((x+2)(x-1)(x-4)^2)/((x+2)^2(x-1)(x-4))
