eg) x^2 + 6x + 9
then after entering the above I can use "calc" to specify that x = 2 say, and it'll spit out the answer to the above equation.

Since you mentioned the 35s: Enter an equation into the equation editor. Pressing Enter or XEQ(*) on viewing this equation causes the calculator to request a value for x and subsequently calculates the result.

(*) XEQ is special as it conveniently evaluates equations also. Please have a look at the 35s manual which is available online - http://www.hp.com/ctg/Manual/c01579350.pdf
