1. Problem Description

The problem asks us to find all roots of the equation x368x=x23\frac{x^3}{6} - 8x = \frac{x^2}{3}.

2. Solution Steps

First, let's multiply both sides of the equation by 6 to eliminate the fractions:
6(x368x)=6(x23)6(\frac{x^3}{6} - 8x) = 6(\frac{x^2}{3})
x348x=2x2x^3 - 48x = 2x^2
Next, let's move all terms to one side of the equation:
x32x248x=0x^3 - 2x^2 - 48x = 0
Now, we can factor out an xx from the equation:
x(x22x48)=0x(x^2 - 2x - 48) = 0
We can further factor the quadratic expression:
x(x8)(x+6)=0x(x-8)(x+6) = 0
Finally, we can find the roots by setting each factor equal to zero:
x=0x = 0
x8=0    x=8x - 8 = 0 \implies x = 8
x+6=0    x=6x + 6 = 0 \implies x = -6
Therefore, the roots are x=0,x=8,x=6x = 0, x = 8, x = -6.

3. Final Answer

x=6,0,8x = -6, 0, 8
