Simplifying
(3u2 + -6u + 5) + (-2u2 + 7u + 1) = 0

Reorder the terms:
(5 + -6u + 3u2) + (-2u2 + 7u + 1) = 0

Remove parenthesis around (5 + -6u + 3u2)
5 + -6u + 3u2 + (-2u2 + 7u + 1) = 0

Reorder the terms:
5 + -6u + 3u2 + (1 + 7u + -2u2) = 0

Remove parenthesis around (1 + 7u + -2u2)
5 + -6u + 3u2 + 1 + 7u + -2u2 = 0

Reorder the terms:
5 + 1 + -6u + 7u + 3u2 + -2u2 = 0

Combine like terms: 5 + 1 = 6
6 + -6u + 7u + 3u2 + -2u2 = 0

Combine like terms: -6u + 7u = 1u
6 + 1u + 3u2 + -2u2 = 0

Combine like terms: 3u2 + -2u2 = 1u2
6 + 1u + 1u2 = 0

Solving
6 + 1u + 1u2 = 0

Solving for variable 'u'.

Begin completing the square.

Move the constant term to the right:

Add '-6' to each side of the equation.
6 + 1u + -6 + u2 = 0 + -6

Reorder the terms:
6 + -6 + 1u + u2 = 0 + -6

Combine like terms: 6 + -6 = 0
0 + 1u + u2 = 0 + -6
1u + u2 = 0 + -6

Combine like terms: 0 + -6 = -6
1u + u2 = -6

The u term is 1u.  Take half its coefficient (0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
u + 0.25 + u2 = -6 + 0.25

Reorder the terms:
0.25 + u + u2 = -6 + 0.25

Combine like terms: -6 + 0.25 = -5.75
0.25 + u + u2 = -5.75

Factor a perfect square on the left side:
(u + 0.5)(u + 0.5) = -5.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
