3-(x+2)=2x(-x+3)

Solution for 3-(x+2)=2x(-x+3) equation:

Simplifying
3 + -1(x + 2) = 2x(-1x + 3)

Reorder the terms:
3 + -1(2 + x) = 2x(-1x + 3)
3 + (2 * -1 + x * -1) = 2x(-1x + 3)
3 + (-2 + -1x) = 2x(-1x + 3)

Combine like terms: 3 + -2 = 1
1 + -1x = 2x(-1x + 3)

Reorder the terms:
1 + -1x = 2x(3 + -1x)
1 + -1x = (3 * 2x + -1x * 2x)
1 + -1x = (6x + -2x2)

Solving
1 + -1x = 6x + -2x2

Solving for variable 'x'.

Combine like terms: -1x + -6x = -7x
1 + -7x + 2x2 = 6x + -2x2 + -6x + 2x2

Reorder the terms:
1 + -7x + 2x2 = 6x + -6x + -2x2 + 2x2

Combine like terms: 6x + -6x = 0
1 + -7x + 2x2 = 0 + -2x2 + 2x2
1 + -7x + 2x2 = -2x2 + 2x2

Combine like terms: -2x2 + 2x2 = 0
1 + -7x + 2x2 = 0

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

Divide each side by '2'.
0.5 + -3.5x + x2 = 0

Move the constant term to the right:

Add '-0.5' to each side of the equation.
0.5 + -3.5x + -0.5 + x2 = 0 + -0.5

Reorder the terms:
0.5 + -0.5 + -3.5x + x2 = 0 + -0.5

Combine like terms: 0.5 + -0.5 = 0.0
0.0 + -3.5x + x2 = 0 + -0.5
-3.5x + x2 = 0 + -0.5

Combine like terms: 0 + -0.5 = -0.5
-3.5x + x2 = -0.5

The x term is -3.5x.  Take half its coefficient (-1.75).
Square it (3.0625) and add it to both sides.

Add '3.0625' to each side of the equation.
-3.5x + 3.0625 + x2 = -0.5 + 3.0625

Reorder the terms:
3.0625 + -3.5x + x2 = -0.5 + 3.0625

Combine like terms: -0.5 + 3.0625 = 2.5625
3.0625 + -3.5x + x2 = 2.5625

Factor a perfect square on the left side:
(x + -1.75)(x + -1.75) = 2.5625

Calculate the square root of the right side: 1.600781059
