You can put this solution on YOUR website!
Should the equation be:
\n" ); document.write( " x^2-4x-5=0 ??
\n" ); document.write( ".
\n" ); document.write( "If so,
\n" ); document.write( "x^2-4x-5=0
\n" ); document.write( "Factoring:
\n" ); document.write( "(x-5)(x+1)=0
\n" ); document.write( "Set each factor equal to zero and solve for x:
\n" ); document.write( "x-5=0
\n" ); document.write( "x=5
\n" ); document.write( ".
\n" ); document.write( "and
\n" ); document.write( ".
\n" ); document.write( "x+1=0
\n" ); document.write( "x=-1
\n" ); document.write( "Check each answer by plugging values of x back into the original equation:
\n" ); document.write( "x^2-4x-5=0
\n" ); document.write( "(5)^2-4(5)-5=0
\n" ); document.write( "25-20-5=0
\n" ); document.write( "0=0 This value checks out.
\n" ); document.write( ".
\n" ); document.write( "x^2-4x-5=0
\n" ); document.write( "(-1)^2-4(-1)-5=0
\n" ); document.write( "1+4-5=0
\n" ); document.write( "5-5=0
\n" ); document.write( "0=0 This value also checks out.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
