Solve for x: $\"x%5E3+%2B+4x%5E2+-+9x+-36+=+0\"$
\n" ); document.write( " $\"%28x%5E3+%2B+4x%5E2%29+-+%289x+%2B+36%29+=+0\"$
\n" ); document.write( " $\"%28x%5E2%29%28x+%2B+4%29+-+9%28x+%2B+4%29+=+0\"$
\n" ); document.write( " $\"%28x+%2B+4%29%28x%5E2+-+9%29+=+0\"$
\n" ); document.write( " $\"%28x+%2B+4%29%28x+-+3%29%28x+%2B+3%29+=+0\"$
\n" ); document.write( "x = -4, 3, -3
\n" ); document.write( "the zeros are -4, 3, and -3. \n" ); document.write( "

\n" );
