Step 1.1

Subtract $b x$ from both sides of the equation.

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

Step 1.2

Subtract $c$ from both sides of the equation.

$a x^{2} = - b x - c$

Step 2

Divide each term in $a x^{2} = - b x - c$ by $x^{2}$ and simplify.

Step 2.3.1.1.2.1

Factor $x$ out of $x^{2}$ .

$a = \frac{x (- b)}{x \cdot x} + \frac{- c}{x^{2}}$

Step 2.3.1.1.2.2

Cancel the common factor.

$a = \frac{x (- b)}{x \cdot x} + \frac{- c}{x^{2}}$

Step 2.3.1.1.2.3

Rewrite the expression.

$a = \frac{- b}{x} + \frac{- c}{x^{2}}$

Step 2.3.1.2

Move the negative in front of the fraction.

$a = - \frac{b}{x} + \frac{- c}{x^{2}}$

Step 2.3.1.3

Move the negative in front of the fraction.

$a = - \frac{b}{x} - \frac{c}{x^{2}}$
