Algebra.Com's Answer #644241 by Natolino1983(23) ![]() You can put this solution on YOUR website! P(x)=x^3+3x^2+mx+6. \n" ); document.write( "P(-2) = -8+12-2m+6 =10-2m =14 then, 2m=-4, m=-2.\r \n" ); document.write( "\n" ); document.write( "Obs:Remainder (P(x)/(x-a)) =P(a).\r \n" ); document.write( "\n" ); document.write( "Answer is m=-2 (E) \n" ); document.write( " |
