it works when i divide trinomial by a binomial but it doesnt seem to work when i divide polynomial with 4 monomials by a binomial

this one works well

this one doesnt seem to work

doesnt seem to work as well

any1 plz help me

and any1 plz xplain the different btween command "factor" and "rFactor", "expand" and "tExpand", "solve", "dSolve" and "rSolve"

thx !

Hi. :)
To divide a polynomial, the best function is propFrac ( in Action/Transformation ). This functions will suit your needs. ( I guess that you use simplify func, right? It just works when there is no remainder in calculation ).
-factor: factor an expression.
-rFactor : can be simply though to factor as much as possible.
-expand: syntax: expand(exp) => normal expandation or expand(exp,var) => special expand. Ex: expand(1/((x+1)(x-1)),x) => 1/(2(x-1))-1/(2(x+1)).
-solve, dSolve and rSolve : solving equation or inequation, solving differential equation, solve sequence formula.
-tExpand: trigonometric expand.
