" 7."56.(1)/(2a+b+2x)=(1)/(2a)+(1)/(b)+(1)/(2x)

Solve for: (1)/(2a+b+2x)=(1)/(2a)+(1)/(b)+(1)/(2x)

Solve for: 1/(2a+b+2x)=1/(2a)+1/b+1/(2x)

If A=(2x+1)/(2x-1), B=(2x-1)/(2x+1) find (1)/(A-B)-(2B)/(A^(2)-B^(2))

If (1)/((1+2x)(1-x^(2)))=(A)/(1+2x)+(B)/(1+x)+(C)/(1-x) then assending order of A, B, C.

If (1)/((1+2x)(1-x^(2)))=(A)/(1+2x)+(B)/(1+x)+(C)/(1-x) then assending order of A, B, C.

The range of the function f(x)=(x^(2)+x+2)/(x^(2)+x+1),x in R, is (1,oo)(b)(1,(11)/(7))(1,(7)/(3)) (d) (1,(7)/(5))
