Solution for 30-x+x^2=0 equation:


Simplifying
30 + -1x + x2 = 0

Solving
30 + -1x + x2 = 0

Solving for variable 'x'.

Begin completing the square.

Move the constant term to the right:

Add '-30' to each side of the equation.
30 + -1x + -30 + x2 = 0 + -30

Reorder the terms:
30 + -30 + -1x + x2 = 0 + -30

Combine like terms: 30 + -30 = 0
0 + -1x + x2 = 0 + -30
-1x + x2 = 0 + -30

Combine like terms: 0 + -30 = -30
-1x + x2 = -30

The x term is -1x.  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.
-1x + 0.25 + x2 = -30 + 0.25

Reorder the terms:
0.25 + -1x + x2 = -30 + 0.25

Combine like terms: -30 + 0.25 = -29.75
0.25 + -1x + x2 = -29.75

Factor a perfect square on the left side:
(x + -0.5)(x + -0.5) = -29.75

Can't calculate square root of the right side.
