**MathMate**, Tuesday, September 22, 2009 at 6:37pmYour answer expands to

5*x^3-10*x^2+3*x-6

Could you check the question if the coefficient is not 3x instead of 43x.

The expression as in the qustion has no rational factors, so there is probably a typo somewhere.

Yes, your answer is half-way, if not more, to factorizing completely.

**MathMate**, Tuesday, September 22, 2009 at 10:10pmIf it is a 3x and not 43x, then you only have to continue your factorization:

5x(x^2+-2x)+3(x-2)

=5x(x^2-2x)+3(x-2)

=5x²(x-2) + 3(x-2)

=(5x²+3)(x-2)

which is the correct answer.

Check:

(5x²+3)(x-2)

=5x³ -10² + 3x -6 OK
