Algebra.Com's Answer #819999 by Alan3354(69443) You can put this solution on YOUR website! In the following problem:\r \n" ); document.write( "\n" ); document.write( "3(x+4)(x+7)\r \n" ); document.write( "\n" ); document.write( "To obtain a correct solution why must you multiply the binomials\r \n" ); document.write( "\n" ); document.write( "Instead of distributing 3 to the first ? If you do this, it comes up incorrect. \n" ); document.write( "=================== \n" ); document.write( "Makes no difference what you do first. \n" ); document.write( "3(x+4)(x+7) = (3x+12)*(x+7) = 3x^2 + 33x + 84 \n" ); document.write( "--- \n" ); document.write( "3(x+4)(x+7) = (x+4)*(3x+21) = 3x^2 + 33x + 84 \n" ); document.write( "--- \n" ); document.write( "3(x+4)(x+7) = 3(x^2+11X+28) = 3x^2 + 33x + 84 \n" ); document.write( "================ \n" ); document.write( "The only possible mistake is to multiply both binomials by 3. \n" ); document.write( " |
