\"6w%5E4-54w%5E2\"
\n" ); document.write( "The coefficients are both multiples of \"6\", because \"-54=6%2A%28-9%29\", so we could take out \"6\" as a common factor.
\n" ); document.write( "Both terms have powers of \"w\", and the smallest exponent is \"2\", and we can write \"w%5E4\" as \"w%5E2%2Aw%5E2=w%5E4\", so we could take out \"w%5E2\" as a common factor.
\n" ); document.write( "We can take out both actors at the same time, as \"6w%5E2\"
\n" ); document.write( "\"6w%5E4=6w%5E2%2Aw%5E2\" and \"-54w%5E2=6W%5E2%2A%28-9%29\"
\n" ); document.write( "\"6w%5E4-54w%5E2=6w%5E2%28w%5E2-9%29\"
\n" ); document.write( "Next, we realize that \"w%5E2-9\" is a difference of squares, a special product of the form
\n" ); document.write( "\"a%5E2-b%5E2=%28a%2Bb%29%28a-b%29\".
\n" ); document.write( "Specifically, \"w%5E2-9=%28w%2B3%29%28w-3%29\".
\n" ); document.write( "So the complete factorization is
