Algebra.Com's Answer #214392 by richwmiller(17219)![]() ![]() You can put this solution on YOUR website! As you wrote the problem (15n-2)*(2n^3-3n^2-4n-5) \n" ); document.write( "the multiplication produces \n" ); document.write( "30n^4-49n^3-54n^2-67n+10\r \n" ); document.write( "\n" ); document.write( "10 n^4-19n^3-14n^2-17n+10 comes from (5n-2)*(2n^3-3n^2-4n-5) \n" ); document.write( "10n4 - 19n3 - 26n2 - 33n - 7 has no factors \n" ); document.write( "10n4 - 15n3 - 20n2 - 25n + 10 has 5 as a factor \n" ); document.write( "4n3 - 6n2 + 8n + 10 has 2 as a factor \n" ); document.write( "You might double check whether it is 15n-2 or 5n-2 \n" ); document.write( "For those of you wondering, there was a typo. It should have been 5n-2. \n" ); document.write( " |
