x2 = (-45 + 9x)

Solving
x2 = -45 + 9x

Solving for variable 'x'.

Reorder the terms:
45 + -9x + x2 = -45 + 9x + 45 + -9x

Reorder the terms:
45 + -9x + x2 = -45 + 45 + 9x + -9x

Combine like terms: -45 + 45 = 0
45 + -9x + x2 = 0 + 9x + -9x
45 + -9x + x2 = 9x + -9x

Combine like terms: 9x + -9x = 0
45 + -9x + x2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-45' to each side of the equation.
45 + -9x + -45 + x2 = 0 + -45

Reorder the terms:
45 + -45 + -9x + x2 = 0 + -45

Combine like terms: 45 + -45 = 0
0 + -9x + x2 = 0 + -45
-9x + x2 = 0 + -45

Combine like terms: 0 + -45 = -45
-9x + x2 = -45

The x term is -9x.  Take half its coefficient (-4.5).
Square it (20.25) and add it to both sides.

Add '20.25' to each side of the equation.
-9x + 20.25 + x2 = -45 + 20.25

Reorder the terms:
20.25 + -9x + x2 = -45 + 20.25

Combine like terms: -45 + 20.25 = -24.75
20.25 + -9x + x2 = -24.75

Factor a perfect square on the left side:
(x + -4.5)(x + -4.5) = -24.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
