Answer:
The distributive property needs to be applied to determine the value to add to the left side of the equation to balance the sides of the equation
Step-by-step explanation:
There is a factor of a outside of the parentheses on the right has side
We are really adding a( b^2/4a^2) to the right side
Simplifying we are adding b^2 /4a
This is what we need to add to the left side to be fair and equal.
We used the distributive property to determine what we were actually adding to the right side.
