Solution for r^2+8r+33= equation:

Simplifying
r2 + 8r + 33 = 0

Reorder the terms:
33 + 8r + r2 = 0

Solving
33 + 8r + r2 = 0

Solving for variable 'r'.

Begin completing the square.

Move the constant term to the right:

Add '-33' to each side of the equation.
33 + 8r + -33 + r2 = 0 + -33

Reorder the terms:
33 + -33 + 8r + r2 = 0 + -33

Combine like terms: 33 + -33 = 0
0 + 8r + r2 = 0 + -33
8r + r2 = 0 + -33

Combine like terms: 0 + -33 = -33
8r + r2 = -33

The r term is 8r.  Take half its coefficient (4).
Square it (16) and add it to both sides.

Add '16' to each side of the equation.
8r + 16 + r2 = -33 + 16

Reorder the terms:
16 + 8r + r2 = -33 + 16

Combine like terms: -33 + 16 = -17
16 + 8r + r2 = -17

Factor a perfect square on the left side:
(r + 4)(r + 4) = -17

Can't calculate square root of the right side.
