find all zeros
\n" ); document.write( "1.f(x)= x^4+2x^3-11x^2+8x-60
\n" ); document.write( "I graphed it and found Real zeroes at x=-5 and x=3
\n" ); document.write( "Using synthetic division you can find the quadratic factor:
\n" ); document.write( "-5)....1....2....-11....8....-60
\n" ); document.write( "........1....-3.....4....-12...|..0
\n" ); document.write( "3).......1......0.....4.....0\r
\n" ); document.write( "\n" ); document.write( "------------
\n" ); document.write( "Remainder: 0
\n" ); document.write( "Quotient : x^2+4
\n" ); document.write( "Factors of the Quotient: (x-2i)(x+2i)
\n" ); document.write( "------------------
\n" ); document.write( "Zeroes: -5,3,2i,-2i
\n" ); document.write( "==========================
\n" ); document.write( "2.f(x)= x^4-8x^3-8x^22x^2-8x-39\r
\n" ); document.write( "\n" ); document.write( "Comment: There is some confusion in your posting
\n" ); document.write( "for #2.
\n" ); document.write( "=============================
