I assume that the equation you mean is below:
[tex] \large \boxed{w + \frac{ {w}^{2} }{3} = 0}[/tex]
To find roots for this equation, we have to get rid of the denominator. We can do by multiplying both sides by 3.
[tex] \large{w(3) + \frac{ {w}^{2} }{3} (3) = 0(3)} \\ \large{3w + {w}^{2} = 0}[/tex]
Factor w-term out (common factor)
[tex] \large{w(3 + w) = 0} \\ \large{w = 0 \: \: \: or \: \: \: 3 + w = 0} \\ \large{w = 0, - 3}[/tex]
Answer
- The roots of quadratic equation are 0,-3
