Algebra.Com's Answer #56046 by bucky(2189)![]() ![]() ![]() You can put this solution on YOUR website! Is the equation like this: \n" ); document.write( ". \n" ); document.write( "(7x^3-9x^2+5x-3)- (3x^3+3x^2+3) <=== not like this \n" ); document.write( ". \n" ); document.write( "or is the equation written like this: \n" ); document.write( ". \n" ); document.write( "(3x^3+3x^2+3) - (7x^3-9x^2+5x-3) <=== like this ... use this one \n" ); document.write( ". \n" ); document.write( "Think of it this way ... suppose the problem had said \"Subtract 10 from 20\". Or maybe \n" ); document.write( "take 10 away from 20. You would have recognized right off that this meant 20 - 10. \n" ); document.write( ". \n" ); document.write( "Even if it had said take 20 away from 10 you might not have questioned that it meant \n" ); document.write( ". \n" ); document.write( "10 - 20 \n" ); document.write( ". \n" ); document.write( "Hope this helps you to see why the second choice you presented was the correct one. It \n" ); document.write( "would be comparable to using the words: \n" ); document.write( ". \n" ); document.write( "Take 7x^3-9x^2+5x-3 away from 3x^3+3x^2+3 \n" ); document.write( ". \n" ); document.write( "Since you didn't ask for help other than getting things in the right order, I presume \n" ); document.write( "that you can do the actual subtraction itself. If not, post again. \n" ); document.write( " |
