Write in Standard Form -8x^2-5x-16=-4x^2

$- 8 x^{2} - 5 x - 16 = - 4 x^{2}$

Add $4 x^{2}$ to both sides of the equation.

$- 8 x^{2} - 5 x - 16 + 4 x^{2} = 0$

Add $- 8 x^{2}$ and $4 x^{2}$ .

$- 4 x^{2} - 5 x - 16 = 0$

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

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

The standard form is $- 4 x^{2} - 5 x - 16$ .

$- 4 x^{2} - 5 x - 16 = 0$
