Answer

Explanation:

Step1: Analyze the equation transformation

Starting with $0 = ax^{2}+bx + c$, to get $-c=ax^{2}+bx$, we subtract $c$ from both sides of the equation.

Step2: Recall equality - property

The property that allows us to subtract the same value from both sides of an equation is the subtraction property of equality.

Answer:

subtraction property of equality
