explain how to compute the xy term of the product (3x4y)^2?
if possible with solution please.... its urgent

Math urgent  David Q, Sunday, September 7, 2008 at 5:08pm
(3x4y)² = (3x4y)(3x4y)
To get the xy term, just multiply each term in the first bracket by each term in the second, and add together all the terms in xy that you find. You should get...
9x²  12xy  12xy + 16y².
So just add the two xy terms together.

You could use FOIL (first, outer,inner last) giving what David Q. said
or
You could use the distributive property
(amounts to the same thing really)
3x(3x4y) 4y(3x4y)
that makes it clear that the xy terms ar
12xy12xy = 24xy
which we already knew of course.
