\n" ); document.write( "Hi,
\n" ); document.write( "Use the rational root theorem
\n" ); document.write( "IF f(x)=x^2+2x+1 = 0 Green
\n" ); document.write( "(x+1)(x+1)=0 |x = -1 is the single rational solution\r
\n" ); document.write( "\n" ); document.write( "IF f(x)=x^2-2x+5 = 0 Blue
\n" ); document.write( "(x-1)^2 + 4 =0 Completing the square
\n" ); document.write( "|x = 1 ± 2i NO rational roots\r
\n" ); document.write( "\n" ); document.write( "IF f(x)=x^2+4x-5 = 0 Purple
\n" ); document.write( "(x+5)(x-1)= 0
\n" ); document.write( "(x+5)= 0
\n" ); document.write( " x = -5
\n" ); document.write( "(x-1)= 0
\n" ); document.write( " x = 1
\n" ); document.write( "x = -5 and x = 1 are the rational solutions
\n" ); document.write( "
