$- 9 - x + x^{2} = - 5 x$

Step 1

Add $5 x$ to both sides of the equation.

$- 9 - x + x^{2} + 5 x = 0$

Step 2

Add $- x$ and $5 x$ .

$- 9 + x^{2} + 4 x = 0$

Step 3

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

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

Step 4

Move $- 9$ .

$x^{2} + 4 x - 9 = 0$
