Hello! \n" ); document.write( "As you mentioned, this problem can be solved using the FOIL method. However, since there are two trinomials, it cna become a bit cumbersome. So let's do it like this. First, let's split the expression by multiplying each term in the 1st trinomial by the whole 2nd trinomial:\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "\n" ); document.write( "And then use the distributive property for each:\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "\n" ); document.write( "And finally, group like terms:\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So the correct answer is B\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "I hope this helps! \n" ); document.write( "Get more answers at Online Math Answers.com! \n" ); document.write( " \n" ); document.write( " |
