\n" ); document.write( "\n" ); document.write( "Now, after factoring by grouping, I got that the zeros are -3, -2, 2, and 3. But the closest choice on my multiple choice homework doesn't show that as an option, the closest one is what I got, but also a zero. Did I do something wrong or am I missing something that a zero is one of the zeros of the equation? \n" ); document.write( "
