Given that the polynomial function has the given zero, find the other zeros.
\n" ); document.write( "f(x)= $\"x%5E3-3x%5E2-5x%2B39\"$ -3 is a zero.
\n" ); document.write( "------------------
\n" ); document.write( "Using synthetic division:
\n" ); document.write( "-3)....1....-3....-5....39
\n" ); document.write( "........1.....-6....13..|..0\r
\n" ); document.write( "\n" ); document.write( "Solve x^2 - 6x + 13 = 0
\n" ); document.write( "x = [6 +- sqrt(36 - 4*13)]/2
\n" ); document.write( "---
\n" ); document.write( "x = [ 6 +- sqrt(-16)]/2
\n" ); document.write( "---
\n" ); document.write( "x = [6 +- 4i]/2
\n" ); document.write( "------
\n" ); document.write( "x = 3 + 2i or x = 3 - 21
