Write in Standard Form -3x-4x^2-5x^5+6x^3

$- 3 x - 4 x^{2} - 5 x^{5} + 6 x^{3}$

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

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

Move $- 3 x$ .

$- 4 x^{2} - 5 x^{5} + 6 x^{3} - 3 x$

Move $- 4 x^{2}$ .

$- 5 x^{5} + 6 x^{3} - 4 x^{2} - 3 x$
