Write in Standard Form -9x+2x^2-18=-3x

$- 9 x + 2 x^{2} - 18 = - 3 x$

Add $3 x$ to both sides of the equation.

$- 9 x + 2 x^{2} - 18 + 3 x = 0$

Add $- 9 x$ and $3 x$ .

$- 6 x + 2 x^{2} - 18 = 0$

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

$a x^{2} + b x + c = 0$

Reorder $- 6 x$ and $2 x^{2}$ .

$2 x^{2} - 6 x - 18 = 0$
