Question

Factor the expression: x3 + 2x2 - 3x - 6

Answer 1

Please help

Answer 2

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)

Answer 3

\[\Large x^3 + 2x^2 - 3x - 6\]


\[\Large (x^3 + 2x^2) + (-3x - 6)\]


\[\Large x^2(x + 2) -3(x + 2)\]


\[\Large (x^2-3)(x + 2)\]

Answer 4

So what would I put down as the answer?

Answer 5

jim is right

Answer 6

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

Thank ya'll :)
