Question 779056: What values of x satisfy the equation:
I have completely forgotten how to even begin to search for x and would love an explanation on how to do it. Thank you! Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! 3x^3 - 5x^2 = 4x
------
Rearrange::
3x^3 - 5x^2 - 4x = 0
-----
Factor:
x(3x^2 -5x -4) = 0
------
Solve: 3x^2 -5x -4 = 0 using the Quadratic Formula:
x = [5 +- sqrt(25-4*3*-4)]/6
x = [5 +- sqrt(73)]/6
-----
Solutions are: x = 0 or x = (5/6)+(1/6)sqrt(73) or x = (5/6)-(1/6)sqrt(73)
