Algebra.Com's Answer #589922 by Theo(13342)![]() ![]() You can put this solution on YOUR website! 2x^2 - 22x - 24 = 2 * (x^2 - 11x - 12) = 2 * (x-12) * (x+1)\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "you confirm by multiplying the factors out to see if you get back to the original equation.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "(x-12) * (x+1) is equal to x^2 + x - 12x - 12 which is equal to x^2 - 11x - 12.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "(x^2 - 11x - 12) * 2 = 2x^2 - 22x - 24.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "looks like we did good.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "here's a lesson on how to factor that might be helpful.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "http://www.purplemath.com/modules/factquad.htm\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
