Solution for 4u^2+2u+3=0 equation:


Simplifying
4u2 + 2u + 3 = 0

Reorder the terms:
3 + 2u + 4u2 = 0

Solving
3 + 2u + 4u2 = 0

Solving for variable 'u'.

Begin completing the square.  Divide all terms by
4 the coefficient of the squared term: 

Divide each side by '4'.
0.75 + 0.5u + u2 = 0

Move the constant term to the right:

Add '-0.75' to each side of the equation.
0.75 + 0.5u + -0.75 + u2 = 0 + -0.75

Reorder the terms:
0.75 + -0.75 + 0.5u + u2 = 0 + -0.75

Combine like terms: 0.75 + -0.75 = 0.00
0.00 + 0.5u + u2 = 0 + -0.75
0.5u + u2 = 0 + -0.75

Combine like terms: 0 + -0.75 = -0.75
0.5u + u2 = -0.75

The u term is 0.5u.  Take half its coefficient (0.25).
Square it (0.0625) and add it to both sides.

Add '0.0625' to each side of the equation.
0.5u + 0.0625 + u2 = -0.75 + 0.0625

Reorder the terms:
0.0625 + 0.5u + u2 = -0.75 + 0.0625

Combine like terms: -0.75 + 0.0625 = -0.6875
0.0625 + 0.5u + u2 = -0.6875

Factor a perfect square on the left side:
(u + 0.25)(u + 0.25) = -0.6875

Can't calculate square root of the right side.

The solution to this equation could not be determined.
