`(y+1)(2y-1)-(3y-1)(y+2)`

If ({(y+1)^(3)+(y-1)^(3)})/(((y+1)^(2)-(y-1)^(2)))=3y then the value of y+(3)/(y) is

If fly)=1-(y-1)+(y-1)^(2)-(y-1)^(3)+...-(y-1) then the coefficient of y^(2) in it is

y-(y-1)/(2)=1-(y-2)/(3)

(x + 2) (x + 1) = (x -2) (x -3) (y+3)(y+2)=(y-1)(y-2)

(4y+1)/(3)+(2y-1)/(2)-(3y-7)/(5)=(47)/(10)

((y^(3)-3y^(2)+5y-1)/(y-1))

The differential equation of all circles in a plane must be (A) y_(3)(1+y_(1)^(2))-3y_(1)y_(2)^(2)=0 (B) Of order 3 and degree 3(C) Of order 3 and degree 2(D)y_(3)(1-y_(1)^(2))-3yy_(2)^(2)=0

Simplify: (y^3-2y^2+3y-4) (y-1) - (24-3)(y^2-y+1)

For all y ne 0, (1)/(y)+(1)/(2y)+(1)/(3y) =

(1)/(y)-(1)/(y-2)=3,y!=0,2
