Question

Find the solutions of the equation.
x^3+3x^2+4x=0

Answer 1

well just factor, you can simplify by taking out an x:
x ( x^2 + 3x - 4) and then factor that into:
x (x+4)(x-1) and then the solution's include 0, -4, and 1

Answer 2

that is not what the back of the book says

Answer 3

what does the back of the book say.

Answer 4

\[0, -\frac{ 3 }{ 2 }\pm \frac{ 1 }{ 2 }, \sqrt{7i} \]

Answer 5

type your equation again please
cause the equation you typed has the answers i provided.

Answer 6

\[x^{3}+3x^{2}+4x=0\]

Answer 7

oh ok..sorry
so you can still factor out the x leaving you with (x^2 + 3x+4) and then use the quadratic formula..do you know the quadratic formula?

Answer 8

yes okay. now I know how they got it
