Solution for X^2=3(X-1) equation:


Simplifying
X2 = 3(X + -1)

Reorder the terms:
X2 = 3(-1 + X)
X2 = (-1 * 3 + X * 3)
X2 = (-3 + 3X)

Solving
X2 = -3 + 3X

Solving for variable 'X'.

Reorder the terms:
3 + -3X + X2 = -3 + 3X + 3 + -3X

Reorder the terms:
3 + -3X + X2 = -3 + 3 + 3X + -3X

Combine like terms: -3 + 3 = 0
3 + -3X + X2 = 0 + 3X + -3X
3 + -3X + X2 = 3X + -3X

Combine like terms: 3X + -3X = 0
3 + -3X + X2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-3' to each side of the equation.
3 + -3X + -3 + X2 = 0 + -3

Reorder the terms:
3 + -3 + -3X + X2 = 0 + -3

Combine like terms: 3 + -3 = 0
0 + -3X + X2 = 0 + -3
-3X + X2 = 0 + -3

Combine like terms: 0 + -3 = -3
-3X + X2 = -3

The X term is -3X.  Take half its coefficient (-1.5).
Square it (2.25) and add it to both sides.

Add '2.25' to each side of the equation.
-3X + 2.25 + X2 = -3 + 2.25

Reorder the terms:
2.25 + -3X + X2 = -3 + 2.25

Combine like terms: -3 + 2.25 = -0.75
2.25 + -3X + X2 = -0.75

Factor a perfect square on the left side:
(X + -1.5)(X + -1.5) = -0.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
