" 14."((x+1)/(x+2))^(2)=(x+2)/(x+4)

Simplify: ((1)/(4)x(2)/(7))-((5)/(14)x(-2)/(3))+((3)/(7)x(9)/(2))

14. int(x^2+x+1)/((x+1)^2(x+2)) dx

The expression ((x^(3) -1)(x^(2) -9x + 14))/((x^(2) + x +1)(x^(2) - 8x + 7)) simplifies to:

(1)/(x+1)+(2)/(x+2)=(4)/(x+4),x!=-1,x!=-2,x!=-4

int ((x ^ (-6) -64) / (4 + 2x ^ (-1) + x ^ (-2)) * (x ^ (2)) / (4-4x ^ (-1) + x ^ (-2))-(4x ^ (2) (2x + 1)) / (1-2x)) dx

int((x^(- 6)-64)/(4+2x^(- 1)+x^(- 2))*(x^2)/(4-4x^(- 1)+x^(- 2))-(4x^2(2x+1))/(1-2x))dx

2(x^(2)+(1)/(x^(2)))-9(x+(1)/(x))+14=0
