Write in Standard Form 3x^3+2x^4-7x+x^2

$3 x^{3} + 2 x^{4} - 7 x + x^{2}$

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

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

Move $- 7 x$ .

$3 x^{3} + 2 x^{4} + x^{2} - 7 x$

Reorder $3 x^{3}$ and $2 x^{4}$ .

$2 x^{4} + 3 x^{3} + x^{2} - 7 x$
