`x^(2)+(1)/(x^(2))-7(x-(1)/(x))+8`

(x^(2))/((x+1)^(2))+((x+1)^(2))/(x^(2))-(x)/(x+1)+(x+1)/(x)-(7)/(4)=p^(2)

" If (3x^(3)-8x^(2)+10)/((x-1)^(4))=(3)/(x-1)+(1)/((x-1)^(2))-(7)/((x-1)^(3))+(k)/((x-1)^(2)) then "k=

The expression (1)/(x-1)-(1)/(x+1)-(2)/(x^(2)+1)-(4)/(x^(4)+1) is equal to (8)/(x^(8)+1)( b) (8)/(x^(8)-1)( c) (8)/(x^(7)-1) (d) (8)/(x^(7)+1)

If x^(2) + (1)/(x^(2))= 7 and x ne 0 , find the value of : 7x^(3) + 8x- (7)/(x^(3))- (8)/(x)

1<(3x^(2)-7x+8)/(x^(2)+1)<2

If x^(2)+(1)/(x^(2))=7 and x!=0: find the value of 7x^(3)+8x-(7)/(x^(3))-(8)/(x)

(17(2-x)-5(x+12))/(1-7x)=8

(2^((3x-1)/(x-1)))^((1)/(3))<8^((x-3)/(3x-7))

1<(3x^(2)-7x+8)/(x^(2)+1)<=2
