Write in Standard Form 3x-5x^2+8x^4-2

$3 x - 5 x^{2} + 8 x^{4} - 2$

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

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

Move $3 x$ .

$- 5 x^{2} + 8 x^{4} + 3 x - 2$

Reorder $- 5 x^{2}$ and $8 x^{4}$ .

$8 x^{4} - 5 x^{2} + 3 x - 2$
