Algebra.Com's Answer #318812 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! use the cubic function f(x)=x^3+x^2-3x+1 to complete the remaining problems \n" ); document.write( "--------------------- \n" ); document.write( "1) what are the possible roots of this function \n" ); document.write( "Possible roots: +1 and -1 \n" ); document.write( "--------------------------- \n" ); document.write( "2)test your possibilities synthetically to determine which one(s) is(are) valid \n" ); document.write( "----- \n" ); document.write( "1)....1....1....-3....1 \n" ); document.write( ".......1....2....-1...|..0\r \n" ); document.write( "\n" ); document.write( "Quotient: x^2+2x-1 \n" ); document.write( "Remainder: 0 \n" ); document.write( "---- \n" ); document.write( "The root is x = 1. \n" ); document.write( "--- \n" ); document.write( "Note: Notice that the coefficients of the cubic add \n" ); document.write( "up to zero. That tells you x = 1 is a root. \n" ); document.write( "==================================================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
