c^3 + c^2 - 7c - 3 = 0, given root -3\r
\n" ); document.write( "\n" ); document.write( "Use synthetic division with x=-3 or use
\n" ); document.write( "long division by x+3.
\n" ); document.write( "The quotient is x^2-2x-1
\n" ); document.write( "which has roots
\n" ); document.write( "x=[2+sqrt(4+4)]/2 = [1+sqrt2]
\n" ); document.write( "or
\n" ); document.write( "x=[2-sqrt(4+4)]/2 = [1-sqrt2]
