Answer:

Third Choice:

x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}

Step-by-step explanation:

One line has

x + \dfrac{b}{2a} = \pm \dfrac{\sqrt{b^2 - 4ac}}{2a}

The next line's reason is that b/2a was subtracted from both sides.

The missing line is:

x = -\dfrac{b}{2a} \pm \dfrac{\sqrt{b^2 - 4ac}}{2a}

Then it simplifies to

x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}
