Solution for x+(x+3)=x*(x+3) equation:


Simplifying
x + (x + 3) = x(x + 3)

Reorder the terms:
x + (3 + x) = x(x + 3)

Remove parenthesis around (3 + x)
x + 3 + x = x(x + 3)

Reorder the terms:
3 + x + x = x(x + 3)

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

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

Solving
3 + 2x = 3x + x2

Solving for variable 'x'.

Combine like terms: 2x + -3x = -1x
3 + -1x + -1x2 = 3x + x2 + -3x + -1x2

Reorder the terms:
3 + -1x + -1x2 = 3x + -3x + x2 + -1x2

Combine like terms: 3x + -3x = 0
3 + -1x + -1x2 = 0 + x2 + -1x2
3 + -1x + -1x2 = x2 + -1x2

Combine like terms: x2 + -1x2 = 0
3 + -1x + -1x2 = 0

Begin completing the square.  Divide all terms by
-1 the coefficient of the squared term: 

Divide each side by '-1'.
-3 + x + x2 = 0

Move the constant term to the right:

Add '3' to each side of the equation.
-3 + x + 3 + x2 = 0 + 3

Reorder the terms:
-3 + 3 + x + x2 = 0 + 3

Combine like terms: -3 + 3 = 0
0 + x + x2 = 0 + 3
x + x2 = 0 + 3

Combine like terms: 0 + 3 = 3
x + x2 = 3

The x term is x.  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.
 + 0.25 + x2 = 3 + 0.25

Combine like terms:  + 0.25 = 1.25
1.25 + x2 = 3 + 0.25

Combine like terms: 3 + 0.25 = 3.25
1.25 + x2 = 3.25

Factor a perfect square on the left side:
(x + 0.5)(x + 0.5) = 3.25

Calculate the square root of the right side: 1.802775638

Break this problem into two subproblems by setting 
(x + 0.5) equal to 1.802775638 and -1.802775638.

Subproblem 1

x + 0.5 = 1.802775638 Simplifying x + 0.5 = 1.802775638 Reorder the terms: 0.5 + x = 1.802775638 Solving 0.5 + x = 1.802775638 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = 1.802775638 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = 1.802775638 + -0.5 x = 1.802775638 + -0.5 Combine like terms: 1.802775638 + -0.5 = 1.302775638 x = 1.302775638 Simplifying x = 1.302775638

Subproblem 2

x + 0.5 = -1.802775638 Simplifying x + 0.5 = -1.802775638 Reorder the terms: 0.5 + x = -1.802775638 Solving 0.5 + x = -1.802775638 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = -1.802775638 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = -1.802775638 + -0.5 x = -1.802775638 + -0.5 Combine like terms: -1.802775638 + -0.5 = -2.302775638 x = -2.302775638 Simplifying x = -2.302775638
