Algebra.Com's Answer #681260 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! Solve the quadratic equation 3x^2+5x+2=0 by factoring \n" ); document.write( "============================== \n" ); document.write( "Similar problem. \n" ); document.write( "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( " |
