Answer 1

Third Choice:

`x = (-b \pm √(b^2 - 4ac))/(2a)`

Explanation:

One line has

`x + (b)/(2a) = \pm (√(b^2 - 4ac))/(2a)`

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

The missing line is:

`x = -(b)/(2a) \pm (√(b^2 - 4ac))/(2a)`

Then it simplifies to

`x = (-b \pm √(b^2 - 4ac))/(2a)`
