Algebra.Com's Answer #681181 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! 7x^2+26x-8 factor the trinomial or state if it's prime. Using the FOIL method \n" ); document.write( "--------- \n" ); document.write( "7x^2+26x-8 \n" ); document.write( "--- \n" ); document.write( "Factoring is to some extent trial and error. \n" ); document.write( "For this one, obviously, it's (x + a)*(7x + b). \n" ); document.write( "The product of a*b = -8, so the signs are different, one + and one minus. \n" ); document.write( "---- \n" ); document.write( "a & b are: \n" ); document.write( "1 & 8 or 2 & 4. \n" ); document.write( "Find the combination that works. \n" ); document.write( "--- \n" ); document.write( "You gain nothing by having someone do it for you. \n" ); document.write( " \n" ); document.write( " |
