1080 + -6r + r2 = 0

Solving for variable 'r'.

Begin completing the square.

Move the constant term to the right:

Add '-1080' to each side of the equation.
1080 + -6r + -1080 + r2 = 0 + -1080

Reorder the terms:
1080 + -1080 + -6r + r2 = 0 + -1080

Combine like terms: 1080 + -1080 = 0
0 + -6r + r2 = 0 + -1080
-6r + r2 = 0 + -1080

Combine like terms: 0 + -1080 = -1080
-6r + r2 = -1080

The r term is -6r.  Take half its coefficient (-3).
Square it (9) and add it to both sides.

Add '9' to each side of the equation.
-6r + 9 + r2 = -1080 + 9

Reorder the terms:
9 + -6r + r2 = -1080 + 9

Combine like terms: -1080 + 9 = -1071
9 + -6r + r2 = -1071

Factor a perfect square on the left side:
(r + -3)(r + -3) = -1071

Can't calculate square root of the right side.

The solution to this equation could not be determined.
