Factoring Special Products
Part 2
"Ok guys this is it,
the last part and it
has to do with
recognizing, and
factoring the
difference of two
squares." "Here we
go, how hard can it
be!" "Here is an
example."
4x^4 - 9y^2
"Ok, the trick is to first of
all make sure you have a
minice sign in the middle,
if you do not you're done;
but we do have a minice
sign in the middle." Next
off your TWO terms must
be perfect squares which
ours are." "So the problem
meets the requirments, so
what is the answer?"
Break up the two terms.
2x^2 - 3y
(2x^2 - 3y)(2x^2 + 3y) "Write the answer in brackets,
then re-write it in brackets exept with a plus sign in
the middle." Thats it!" "Click here TO TRY IT
OUT!"
