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

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

If quad f=(x)/(1+x^(2))+(1)/(3)((x)/(1+x^(2)))^(3)+(1)/(5)((x)/(1+x^(2)))^(5)+ and g=x-(2)/(3)x^(3)+(1)/(5)x^(5)+(1)/(7)x^(7)-.... then

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

2(x-4)/((x-1)(x-7))>=(1)/(x-2)

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

int(5x^(8)+7x^(6))/(x^(2)+1+2x^(7))dx is equal to (a) (x)/(x^(2)+1+2x^(7))+C( b) (x^(7))/(x^(2)+1+2x^(7))+C (c) (x^(6))/(x^(2)+1+2x^(7))+C(d)x^(2)+1+2x^(7)+C
