Simplifying
a2 + a + -3 + -3a2 + -5 = 0

Reorder the terms:
-3 + -5 + a + a2 + -3a2 = 0

Combine like terms: -3 + -5 = -8
-8 + a + a2 + -3a2 = 0

Combine like terms: a2 + -3a2 = -2a2
-8 + a + -2a2 = 0

Solving
-8 + a + -2a2 = 0

Solving for variable 'a'.

Begin completing the square.  Divide all terms by
-2 the coefficient of the squared term: 

Divide each side by '-2'.
4 + -0.5a + a2 = 0

Move the constant term to the right:

Add '-4' to each side of the equation.
4 + -0.5a + -4 + a2 = 0 + -4

Reorder the terms:
4 + -4 + -0.5a + a2 = 0 + -4

Combine like terms: 4 + -4 = 0
0 + -0.5a + a2 = 0 + -4
-0.5a + a2 = 0 + -4

Combine like terms: 0 + -4 = -4
-0.5a + a2 = -4

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.
-0.5a + 0.25 + a2 = -4 + 0.25

Reorder the terms:
0.25 + -0.5a + a2 = -4 + 0.25

Combine like terms: -4 + 0.25 = -3.75
0.25 + -0.5a + a2 = -3.75

Factor a perfect square on the left side:
(a + 0.5)(a + 0.5) = -3.75

Can't calculate square root of the right side.
