Write in Standard Form -2+1/3x^2-x

$- 2 + \frac{1}{3} x^{2} - x$

To write a polynomial in standard form, simplify and then arrange the terms in descending order.

$a x^{2} + b x + c$

Combine $\frac{1}{3}$ and $x^{2}$ .

$- 2 + \frac{x^{2}}{3} - x$

Move $- 2$ .

$\frac{x^{2}}{3} - x - 2$

Reorder terms.

$\frac{1}{3} x^{2} - x - 2$
