Find all zeros of the polynomial equation
\n" ); document.write( "x^3-2x^2+10x+136=0
\n" ); document.write( "----------
\n" ); document.write( "I graphed it and found x=-4 is a zero.
\n" ); document.write( "Use synthetic division to find the other zeroes.
\n" ); document.write( "----------
\n" ); document.write( "-4)....1....-2....10....136
\n" ); document.write( ".........1....-6....34...|..0\r
\n" ); document.write( "\n" ); document.write( "Quotient: x^2 - 6x + 34
\n" ); document.write( "Use the quadratic formula to find remaining zeroes.
\n" ); document.write( "x = [6 +- sqrt(36 -4*1*34)]/2
\n" ); document.write( "x = [6 +- sqrt(-100)]/2
\n" ); document.write( "x = [6 +- 10i]/2
\n" ); document.write( "======================
\n" ); document.write( "Zeroes are x = -4, x = (3+5i), x = (3-5i)
\n" ); document.write( "=========================================
