**MathGuru**, Sunday, May 22, 2011 at 8:25amI assume your problem is this:

2x^2 + 3xy - 4y^2

Note: you can use ^ to mean raised to the power of some value; for example x^2 means x raised to the power of 2 (or x squared).

Substitute 2 for x and -4 for y to evaluate the expression.

I hope this will help get you started.
