If x+2 is a factor of x^3 - ax- 6,then find the remainder when 2x^3+ax^2-6x+9 is divided by x+1.

\n" );
document.write( "Solving this by substituting 0 for f(- 2), and - 2 for x, you will get a = 7.
\n" );
document.write( "Since x + 1 is a factor, then a zero is - 1. You now need to use either POLYNOMIAL LONG DIVISION to DIVIDE  by x + 1, or synthetic division to determine the remainder.
