Actually I'll bet that plenty of people do know but figured you'd look in the manual. The answer is no it does not. It's not difficult to write a program that does.

Use MATH 0: SOLVER

With this application you can solve quadratic equations too.

Earboth, didn't you program a quadratic solver for TIs once?

Well, there is a way i solve quadratics if its on a
ax^2 + bx + c = 0
format.

What i do is put the equation on the y=
and then graph it and and then do 2nd Trace and Zero and make the calculator guess that 0 point on the porabla.
