I entered the equation into a graphing calculator. clicked table and then scrolled down to the profit of $3,563. 55 skateboards
you could also try this equation. B=the number attached to x so 10, a=the number attached to x^2(or in other equation x^3 etc) so 1 and c is the number, so -12.

Find the roots of the quadratic equation w+w²/3=0

Daniel [21]

I assume that the equation you mean is below:

$\large \boxed{w + \frac{ {w}^{2} }{3} = 0}$

To find roots for this equation, we have to get rid of the denominator. We can do by multiplying both sides by 3.

$\large{w(3) + \frac{ {w}^{2} }{3} (3) = 0(3)} \\ \large{3w + {w}^{2} = 0}$

Factor w-term out (common factor)

$\large{w(3 + w) = 0} \\ \large{w = 0 \: \: \: or \: \: \: 3 + w = 0} \\ \large{w = 0, - 3}$

Answer

The roots of quadratic equation are 0,-3
