The equality used is Subtraction property of equality
Option A is correct
Step-by-step explanation:
We need to identify which option best explains or justifies Step 1.
Step 1 is: [tex]-c = ax^2 + bx[/tex]
The given equation is: [tex]0 = ax^2 + bx + c[/tex]
To get the equation for step 1 we need to subtract c on both sides of equation i.e using subtraction property of equality
[tex]0-c = ax^2 + bx + c-c[/tex]
[tex]-c = ax^2 + bx [/tex]
So, The equality used is Subtraction property of equality
Option A is correct.
