I have the following boolean algebra equation:

(A + B + C)(D + ~C)

I don't know if my equation is in standard form, so just to be explicit, by '+' I mean OR and the parenthesis mean AND. ~ is NOT.

My goal/need is to eliminating C from this equation. Is this possible?

I've played around with this, but have been unable to do so. Can anyone help me?

Thank you in advance!

No. If A = 0, B = 0, D = 1, then the expression equals C.
