Session 1.9: Simplification of results

> restart;

> fe1:=x+3*x^2+2*x; <- Expression automatically simplified

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

> normal(fe2); <- Simplified expression using normal

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

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

> simplify(df); <- Simplified version of derivative. Simplify

combined two terms into one
