Algebra.Com's Answer #224522 by rapaljer(4671)![]() ![]() You can put this solution on YOUR website! This is what I call \"Advanced Trinomial Factoring.\" Realize that a TRINOMIAL usually factors into the product of two binomials. \n" ); document.write( "8t^2+8t+9\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "The first times first will probably begin with 4t *2t \n" ); document.write( "(4t+____)(2t+____)\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "The last times last will probably be 3*3. The question is this: Will your middle term come out to 18t. \n" ); document.write( "(4t+3)(2t+3) The middle term is 4t*3 + 3*2t, which is 12t +6t, which is correct 18t, and this is correct.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Final answer (4t+3)(2t + 3) \n" ); document.write( " |
