\"+36x%5E4y%5E2+-+49z%5E4+\"
\n" ); document.write( "this is the difference of two squares and follows the form:
\n" ); document.write( "\"+x%5E2-y%5E2+=+%28x-y%29%28x%2By%29+\"
\n" ); document.write( "find the square root of each term
\n" ); document.write( "\"+%286x%5E2y-7z%5E2%29%286x%5E2y%2B7z%5E2%29+\"
\n" ); document.write( "This is as far as it can be factored\r

\n" ); document.write( "\"+x%5E2+-5x+-14+\"
\n" ); document.write( "With this, as yourself what two numbers, when multiplied give you 14, but when added or subtracted give you 5.
\n" ); document.write( "The answer is 7 and 2.
\n" ); document.write( "\"+%28x-7%29%28x%2B2%29+\"
\n" ); document.write( "The have opposite signs because the 14 is negative. And because the middle term is also negative, the larger of the two values has to be the negative one.
