Determine whether the number -6 is a zero of F(x)=x^3+2x^2-40x+64. If it is, find the other real zeros?
\n" ); document.write( "-----
\n" ); document.write( "Use synthetic division:
\n" ); document.write( "-6)....1....2....-40....64
\n" ); document.write( ".......1....-4...-16...|..160\r
\n" ); document.write( "\n" ); document.write( "---
\n" ); document.write( "Since f(-6) is not zero, -6 is not a zero.
