3a^2+a^2+a+6=

Solution for 3a^2+a^2+a+6= equation:

Simplifying
3a2 + a2 + a + 6 = 0

Reorder the terms:
6 + a + 3a2 + a2 = 0

Combine like terms: 3a2 + a2 = 4a2
6 + a + 4a2 = 0

Solving
6 + a + 4a2 = 0

Solving for variable 'a'.

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

Divide each side by '4'.
1.5 + 0.25a + a2 = 0

Move the constant term to the right:

Add '-1.5' to each side of the equation.
1.5 + 0.25a + -1.5 + a2 = 0 + -1.5

Reorder the terms:
1.5 + -1.5 + 0.25a + a2 = 0 + -1.5

Combine like terms: 1.5 + -1.5 = 0.0
0.0 + 0.25a + a2 = 0 + -1.5
0.25a + a2 = 0 + -1.5

Combine like terms: 0 + -1.5 = -1.5
0.25a + a2 = -1.5

The a term is a.  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.
0.25a + 0.25 + a2 = -1.5 + 0.25

Reorder the terms:
0.25 + 0.25a + a2 = -1.5 + 0.25

Combine like terms: -1.5 + 0.25 = -1.25
0.25 + 0.25a + a2 = -1.25

Factor a perfect square on the left side:
(a + 0.5)(a + 0.5) = -1.25

Can't calculate square root of the right side.
