Simplifying
3x2 + 5x2 + -4x + 5 + -2 = 0

Reorder the terms:
5 + -2 + -4x + 3x2 + 5x2 = 0

Combine like terms: 5 + -2 = 3
3 + -4x + 3x2 + 5x2 = 0

Combine like terms: 3x2 + 5x2 = 8x2
3 + -4x + 8x2 = 0

Solving
3 + -4x + 8x2 = 0

Solving for variable 'x'.

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

Divide each side by '8'.
0.375 + -0.5x + x2 = 0

Move the constant term to the right:

Add '-0.375' to each side of the equation.
0.375 + -0.5x + -0.375 + x2 = 0 + -0.375

Reorder the terms:
0.375 + -0.375 + -0.5x + x2 = 0 + -0.375

Combine like terms: 0.375 + -0.375 = 0.000
0.000 + -0.5x + x2 = 0 + -0.375
-0.5x + x2 = 0 + -0.375

Combine like terms: 0 + -0.375 = -0.375
-0.5x + x2 = -0.375

The x term is -0.5x.  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.
-0.5x + 0.0625 + x2 = -0.375 + 0.0625

Reorder the terms:
0.0625 + -0.5x + x2 = -0.375 + 0.0625

Combine like terms: -0.375 + 0.0625 = -0.3125
0.0625 + -0.5x + x2 = -0.3125

Factor a perfect square on the left side:
(x + -0.25)(x + -0.25) = -0.3125

Can't calculate square root of the right side.

The solution to this equation could not be determined.
