You can put this solution on YOUR website!
for this equation you want to first start out with synthetic division. I am going to assume you know what synthetic division is. \r
\n" ); document.write( "\n" ); document.write( "I am going to start with 1
\n" ); document.write( "1 6 -25 18
\n" ); document.write( "0 1 7 -18
\n" ); document.write( "1 7 -18 R=0
\n" ); document.write( "1 is a zero of the equation (x-1).
\n" ); document.write( "you are left with $\"x%5E2%2B7x-18\"$
\n" ); document.write( "You need to factor it.
\n" ); document.write( "(x+9)(x-2)
\n" ); document.write( "so now you have all the zeros
\n" ); document.write( "f(x)=(x-1)(x+9)(x-2)
\n" ); document.write( "1, -9, 2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "

\n" );
