Answer:
Find a common denominator on the right side of the equation.
Step-by-step explanation:
On the right side of the equation we began with
[tex]-\frac{c}{a} +\frac{b^2}{4a^2}[/tex]
Then we ended with
[tex]-\frac{4ac}{4a^2} +\frac{b^2}{4a^2}[/tex]
As we can see, only the left term changed. It was multiplied by [tex]\frac{4a}{4a}[/tex]. This was done in order to match the denominator of the right term.
As you can see they now match.
