[R] Solving quadratic functions

I'm examining the use of the 'lm' function to solve quadratic functions.
With S+ 2000, the 'lm' function can be used to solve eqns such as x1 + x2 +
x1^2 + x2^2 + x1*x2.
But, when trying this same eqn with R, the software does not produce any
coefficients for x1^2 or x2^2.
Is this a common problem?
I'm using ver. 1.3.1 under Win. 2000.
