## Solution for 2x^2+3x+5=0 equation:

Simplifying
2x2 + 3x + 5 = 0

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

Solving
5 + 3x + 2x2 = 0

Solving for variable 'x'.

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

Divide each side by '2'.
2.5 + 1.5x + x2 = 0

Move the constant term to the right:

Add '-2.5' to each side of the equation.
2.5 + 1.5x + -2.5 + x2 = 0 + -2.5

Reorder the terms:
2.5 + -2.5 + 1.5x + x2 = 0 + -2.5

Combine like terms: 2.5 + -2.5 = 0.0
0.0 + 1.5x + x2 = 0 + -2.5
1.5x + x2 = 0 + -2.5

Combine like terms: 0 + -2.5 = -2.5
1.5x + x2 = -2.5

The x term is 1.5x.  Take half its coefficient (0.75).
Square it (0.5625) and add it to both sides.

Add '0.5625' to each side of the equation.
1.5x + 0.5625 + x2 = -2.5 + 0.5625

Reorder the terms:
0.5625 + 1.5x + x2 = -2.5 + 0.5625

Combine like terms: -2.5 + 0.5625 = -1.9375
0.5625 + 1.5x + x2 = -1.9375

Factor a perfect square on the left side:
(x + 0.75)(x + 0.75) = -1.9375

Can't calculate square root of the right side.
