Factor the expression: x3 + 2x2 - 3x - 6
x^3 + 2x^2 - 3x - 6 x^2(x + 2) - 3(x + 2) (x^2 - 3)(x + 2) (x^2 - 3)(x + 2) or (x + √3)(x - √3)(x + 2)
\[\Large x^3 + 2x^2 - 3x - 6\] \[\Large (x^3 + 2x^2) + (-3x - 6)\] \[\Large x^2(x + 2) -3(x + 2)\] \[\Large (x^2-3)(x + 2)\]
So what would I put down as the answer?
I would stop at \[\Large (x^2-3)(x + 2)\] instead of keep going to get \[\Large (x-\sqrt{3})(x+\sqrt{3})(x + 2)\] because most books I've seen factor over the rationals
