Algebra.Com's Answer #49344 by ankor@dixie-net.com(22740) You can put this solution on YOUR website! One solution of 2x^2+11x+k=0 is -5. Find the other solution. \n" ); document.write( ": \n" ); document.write( "Here's one way. \n" ); document.write( "Use synthetic division: \n" ); document.write( " ________________________ \n" ); document.write( "-5 | 2 + 11 + k \n" ); document.write( "..............-10 - 5 \n" ); document.write( ".....-------------- \n" ); document.write( "..........2...+1 + 0 \n" ); document.write( "Which is (2x + 1) is the other solution \n" ); document.write( ": \n" ); document.write( "We know there is no remainder so: k - 5 = 0; k = +5 \n" ); document.write( ": \n" ); document.write( "FOIL (x+5)(2x + 1) = 2x^2 + 11x + 5 to check it: \n" ); document.write( " |
