You can put this solution on YOUR website!
f(x) = 2x^3 + 11x^2 - 21x - 90. (10)
\n" ); document.write( "a. Use the rational zero test to list all possible rational zeros of f.
\n" ); document.write( "I found these to be x= 3,-5/2,-6
\n" ); document.write( "b. Write f as a product of linear factors algebraically. Show all your work
\n" ); document.write( "including synthetic division.
\n" ); document.write( "

All POSSIBLE rational zeros of f:  ====>    
\n" );
document.write( "That's a total of 48 POSSIBLE ZEROES, but with some factors being duplicates , the number of zeroes decreases. 
\n" );
document.write( "Now, which ones prove to be ACTUAL ZEROES, you've already determined that. \n" );

\n" );
