5x^2-9x+73=0

Solution for 5x^2-9x+73=0 equation:

Simplifying
5x2 + -9x + 73 = 0

Reorder the terms:
73 + -9x + 5x2 = 0

73 + -9x + 5x2 = 0

Solving for variable 'x'.

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

Divide each side by '5'.
14.6 + -1.8x + x2 = 0

Move the constant term to the right:

Add '-14.6' to each side of the equation.
14.6 + -1.8x + -14.6 + x2 = 0 + -14.6

Reorder the terms:
14.6 + -14.6 + -1.8x + x2 = 0 + -14.6

Combine like terms: 14.6 + -14.6 = 0.0
0.0 + -1.8x + x2 = 0 + -14.6
-1.8x + x2 = 0 + -14.6

Combine like terms: 0 + -14.6 = -14.6
-1.8x + x2 = -14.6

The x term is -1.8x.  Take half its coefficient (-0.9).
Square it (0.81) and add it to both sides.

Add '0.81' to each side of the equation.
-1.8x + 0.81 + x2 = -14.6 + 0.81

Reorder the terms:
0.81 + -1.8x + x2 = -14.6 + 0.81

Combine like terms: -14.6 + 0.81 = -13.79
0.81 + -1.8x + x2 = -13.79

Factor a perfect square on the left side:
(x + -0.9)(x + -0.9) = -13.79

Can't calculate square root of the right side.
