Use the quadratic formula to find all roots: f(x)= 2x^3-3x^2-2x+3 \n" ); document.write( ": \n" ); document.write( "Assume one factor is (x+1) \n" ); document.write( ": \n" ); document.write( "use synthetic division \n" ); document.write( ": __________________ \n" ); document.write( " -1|2 -3 -2 + 3 \n" ); document.write( ">>>>>-2 + 5 - 3 \n" ); document.write( " -------------- \n" ); document.write( ">>>2 -5 + 3 + 0 \n" ); document.write( "Now we have (2x^2 - 5x + 3)(x+1) \n" ); document.write( "You can use the quadratic formula to find the other roots \n" ); document.write( "Anyway it will factor to (2x - 3)(x - 1) \n" ); document.write( ": \n" ); document.write( "The three roots, -1, +1, 1.5 \n" ); document.write( " |
