Please help me! I have to find the remaing roots (zeros) but I'm confused. The problem is f(x)=x^3+2x^2-3x+20. One root is there and it is -4.
\n" ); document.write( "OK ..GO AHEAD..YOU SHOULD DIVIDE WITH -4 ..NOT +4....
\n" ); document.write( " I have to find two more roots (zeros). I tried to work it out using synthetic division:
\n" ); document.write( "-4|......... 1.......... , 2......... , -3.......... , 20
\n" ); document.write( "............0.............-4.............8............-20
\n" ); document.write( "--------------------------------------------------------------------------____
\n" ); document.write( ".............1............-2.............5.............0
\n" ); document.write( "ANSWER IS
\n" ); document.write( "X^2-2X+5=THIS HAS IMAGINARY ROOTS.AS DISCRIMINANT IS NEGATIVE...USE QUADRATIC FORMULA...
