Write in Standard Form -5x+4x^2+15=-2

$- 5 x + 4 x^{2} + 15 = - 2$

Add $2$ to both sides of the equation.

$- 5 x + 4 x^{2} + 15 + 2 = 0$

Add $15$ and $2$ .

$- 5 x + 4 x^{2} + 17 = 0$

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

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

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

$4 x^{2} - 5 x + 17 = 0$
