Solving for variable 'r'.

Move all terms containing r to the left, all other terms to the right.

Add '-0.15r2' to each side of the equation.
0.03 + -0.15r2 = 0.15r2 + -0.15r2

Combine like terms: 0.15r2 + -0.15r2 = 0.00
0.03 + -0.15r2 = 0.00

Add '-0.03' to each side of the equation.
0.03 + -0.03 + -0.15r2 = 0.00 + -0.03

Combine like terms: 0.03 + -0.03 = 0.00
0.00 + -0.15r2 = 0.00 + -0.03
-0.15r2 = 0.00 + -0.03

Combine like terms: 0.00 + -0.03 = -0.03
-0.15r2 = -0.03

Divide each side by '-0.15'.
r2 = 0.2

Simplifying
r2 = 0.2

Take the square root of each side:
r = {-0.447213596, 0.447213596}
