\n" ); document.write( "(1) \"Have I answered the 2 product and quotient of each given expression below?\"

\n" ); document.write( "ANSWER: Yes, you have answered them.

\n" ); document.write( "But clearly the question you meant to ask was whether you had answered them CORRECTLY. The answer to that question is NO. (Close, but not quite....)

\n" ); document.write( "(2) Don't mix lower- and upper-case letters when showing algebraic expressions. \"x\" and \"X\" in the same problem can represent different numbers.

\n" ); document.write( "(3) Use parentheses where required. Neither of the expressions you show can be simplified much.

\n" ); document.write( "Here are the expressions you show (except I have corrected \"(x=y)^2\" to \"(x-y)^2\":

\n" ); document.write( "Problem 1:

\n" ); document.write( "\"x%5E2-y%5E2%2F%28x-y%29%5E2\" times \"2x%2B2y%2F3x\"

\n" ); document.write( "Problem 2:

\n" ); document.write( "\"x%5E2%2B3x-28%2Fx%5E2-16\" divided by \"x%5E2-1%2Fx%2B4\"

\n" ); document.write( "Those are obviously not the expressions you meant to show!

\n" ); document.write( "Note your lack of parentheses also makes the answers you show incorrect.

\n" ); document.write( "

\n" ); document.write( "Now to look at the problems you INTENDED to post....

\n" ); document.write( "(1)

\n" ); document.write( "\"%28%28x%5E2-y%5E2%29%2F%28%28x-y%29%5E2%29%29%2A%28%282x%2B2y%29%2F3x%29\"

\n" ); document.write( "\"%28%28x%2By%29%28x-y%29%282%29%28x%2By%29%29%2F%28%28x-y%29%28x-y%29%283x%29%29\"

\n" ); document.write( "The only common factor between numerator and denominator is (x-y):

\n" ); document.write( "ANSWER: \"%282%28x%2By%29%5E2%29%2F%28%283x%29%28x-y%29%29\"

\n" ); document.write( "So your answer on that one was right, except that the factor (2x+2y) should be factored further.

\n" ); document.write( "(2)

\n" ); document.write( "\"%28%28x%5E2%2B3x-28%29%2F%28x%5E2-16%29%29%2F%28%28x%5E2-1%29%2F%28x%2B4%29%29\"

\n" ); document.write( "\"%28%28x%5E2%2B3x-28%29%2F%28x%5E2-16%29%29%2A%28%28x%2B4%29%2F%28x%5E2-1%29%29\"

\n" ); document.write( "\"%28%28x%2B7%29%28x-4%29%28x%2B4%29%29%2F%28%28x%2B4%29%28x-4%29%28x%2B1%29%28x-1%29%29\"

\n" ); document.write( "The (x+4) and (x-4) factors all cancel

\n" ); document.write( "\"%28x%2B7%29%2F%28%28x%2B1%29%28x-1%29%29\"

\n" ); document.write( "ANSWER: \"%28x%2B7%29%2F%28x%5E2-1%29\"

\n" ); document.write( "So your answer for that one was right.


\n" ); document.write( "Final summary:

\n" ); document.write( "Your algebra is mostly correct....

\n" ); document.write( "But take the time to make your post using correct language, and using parentheses where required.
