How do i factorise 25p^2-q^2?
- Math - PsyDAG, Wednesday, June 24, 2009 at 1:11pm
The middle term must cancel out in terms of the factors, so if one factor has a negative term, the other would have a positive term (-q and +q). You should be able to figure it out from that.
I hope this helps. Thanks for asking.
