Solving
384.16 = 19.6v + -1v2

Solving for variable 'v'.

Reorder the terms:
384.16 + -19.6v + v2 = 19.6v + -19.6v + -1v2 + v2

Combine like terms: 19.6v + -19.6v = 0.0
384.16 + -19.6v + v2 = 0.0 + -1v2 + v2
384.16 + -19.6v + v2 = -1v2 + v2

Combine like terms: -1v2 + v2 = 0
384.16 + -19.6v + v2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-384.16' to each side of the equation.
384.16 + -19.6v + -384.16 + v2 = 0 + -384.16

Reorder the terms:
384.16 + -384.16 + -19.6v + v2 = 0 + -384.16

Combine like terms: 384.16 + -384.16 = 0.00
0.00 + -19.6v + v2 = 0 + -384.16
-19.6v + v2 = 0 + -384.16

Combine like terms: 0 + -384.16 = -384.16
-19.6v + v2 = -384.16

The v term is -19.6v.  Take half its coefficient (-9.8).
Square it (96.04) and add it to both sides.

Add '96.04' to each side of the equation.
-19.6v + 96.04 + v2 = -384.16 + 96.04

Reorder the terms:
96.04 + -19.6v + v2 = -384.16 + 96.04

Combine like terms: -384.16 + 96.04 = -288.12
96.04 + -19.6v + v2 = -288.12

Factor a perfect square on the left side:
(v + -9.8)(v + -9.8) = -288.12

Can't calculate square root of the right side.

The solution to this equation could not be determined.
