Write in Standard Form -1/10-x^3+x^4+3x

$- \frac{1}{10} - x^{3} + x^{4} + 3 x$

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

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

Move $- \frac{1}{10}$ .

$- x^{3} + x^{4} + 3 x - \frac{1}{10}$

Reorder $- x^{3}$ and $x^{4}$ .

$x^{4} - x^{3} + 3 x - \frac{1}{10}$
