Session 1.9: Simplification of results

> restart;

>fe1:=x+3*x^2+2*x; Some expressions automatically simplify

fe1 := 3*x+3*x^2

>fe2:=x+3*(x+1)^2; Expression requires simplification

fe2 := x+3*(x+1)^2

>normal(fe2);  Simplified expression using normal

7*x+3*x^2+3

>f:=(a+b*x)/(c+d*x); Initial expression

f := (a+b*x)/(c+d*x)

>df:=diff(f,x); Unsimplified derivative of expression.

                                                                       

df := b/(c+d*x)-(a+b*x)*d/(c+d*x)^2

>simplify(df); Simplified version of derivative.  Simplify combined two terms into one

-(-b*c+d*a)/(c+d*x)^2
