and try

Answer 2

so i have to foil? @sail1234

Answer 3

5/(x+1)(x-1)-2/(x+1)=2/x
can u proceed

Answer 4

i got x^2-1=x^2-1

Answer 5

5-2(x-1)/(x+1)(x-1)=2/x
5-2x+2/x^2-1=2/x
7-2x/x^2-1=2/x
x(7-2x)=2(x^2-1)
can u procced

Answer 6

Answer 9

7x-2x^2=x^2-1
3x^2-7x-1=0
solve this quadratic equation
x=-b+root(d)/2a and -b-root(d)/2a
d=b^2-4ac
