" 6."((x-1)(x+2)^(2))/(-1-x)<0

Solve (2x-3)/(x-1)+1=(6x-x^(2)-6)/(x-1)

(d)/(dx ) { (1)/( 6) log ""((x-1)^(2))/(x ^(2) + x +1 ) + (1)/( sqrt3)Tan ^(-1) ((2x +1)/( sqrt3))}=

Solve for x: (1)/(x-2)+(2)/(x-1)=(6)/(x) ,x ne 0,1,2

Coefficient of x^(6) in (1+x)(1+x^(2))^(2)(1+x^(3))^(3)…(1+x^(n))^(n) is

Add: (3x^(2) - (1)/(5)x + (7)/(3)) + ((-1)/(4)x^(2) + (1)/(3)x - (1)/(6)) + (-2x^(2) - (1)/(2)x + 5)

prove that |(1,x,x+1),(2x,x(x-1),x(x+1)),(3x(1-x),x(x-1)(x-2),x(x+1)(x-1))|=6x^(2)(1-x^(2))

(2x-1)/(2x+1)+(2x+1)/(2x-1)=6
