Find the bounds on the real zeros of the following function. Please show all of your work.
\n" ); document.write( "f(x)=x^5-5x^4+8x+2
\n" ); document.write( "...
\n" ); document.write( "f(x)=x^5-5x^4+8x+2
\n" ); document.write( "factors of p=2: ±1, ±2
\n" ); document.write( "factors of q=1: ±1
\n" ); document.write( "possible rational roots, (p/q): ±1, ±2
\n" ); document.write( "Using synthetic division to find real rational roots
\n" ); document.write( "0).....1....-5.....0.....0.....8.....2
\n" ); document.write( "1).....1....-4....-4...-4....4....6 (root between 1 and -1)
\n" ); document.write( "-1)...1....-6.....6....-6...14..-12 (alternate signs, -1 is lower bound)
\n" ); document.write( "2).....1....-3...-6...-12..-16..-30
\n" ); document.write( "-2)...1....-7...14...-28..64...-126
\n" ); document.write( "No rational roots found.
\n" ); document.write( "
\n" );
