Algebra.Com's Answer #67886 by bucky(2189)![]() ![]() ![]() You can put this solution on YOUR website! Given: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "To perform the operations and simplify completely you first notice that both fractions have \n" ); document.write( "the denominator \n" ); document.write( "single common denominator to get: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "In the numerator the first quantity in parentheses is (2x-1). Since its set of parentheses \n" ); document.write( "is not preceded by a minus sign, you can just remove those parentheses without doing \n" ); document.write( "anything to the terms inside. When you do the problem becomes: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "Notice now the next set of parentheses in the numerator. The terms inside this set of \n" ); document.write( "parentheses are +1 and -x. Since the parentheses are preceded by a minus sign, when you \n" ); document.write( "remove the parentheses you change the sign of all the terms inside. When you do that the \n" ); document.write( "problem then becomes: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "Then you can combine the like terms in the numerator. The +2x and the +x combine to \n" ); document.write( "give +3x and the -1 and -1 combine to give -2. This makes the problem: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "That's the answer to the problem. There are no other cancellations or combinations \n" ); document.write( "that can be made. If you like you can long divide x + 3 into 3x - 2 and the answer you \n" ); document.write( "will get is: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "But that is the same as the answer: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "It's just in a different form. \n" ); document.write( ". \n" ); document.write( "Hope this helps you to understand what the problem is asking for you to do, and provides \n" ); document.write( "you with some insight into how to do the problem too. \n" ); document.write( " \n" ); document.write( " |
