Write in Standard Form 17=5-6x-x^2

$17 = 5 - 6 x - x^{2}$

Move all the expressions to the left side of the equation.

Subtract $5$ from both sides of the equation.

$17 - 5 = - 6 x - x^{2}$

Add $6 x$ to both sides of the equation.

$17 - 5 + 6 x = - x^{2}$

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

$17 - 5 + 6 x + x^{2} = 0$

Subtract $5$ from $17$ .

$12 + 6 x + x^{2} = 0$

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

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

Move $12$ .

$6 x + x^{2} + 12 = 0$

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

$x^{2} + 6 x + 12 = 0$
