Factor a difference between two squares.
(0.04 + d2)(-0.04 + d2) = 0.0000

Factor a difference between two squares.
(0.04 + d2)((0.2 + d)(-0.2 + d)) = 0.0000

Subproblem 1
Set the factor '(0.04 + d2)' equal to zero and attempt to solve:

Simplifying
0.04 + d2 = 0

Solving
0.04 + d2 = 0

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

Add '-0.04' to each side of the equation.
0.04 + -0.04 + d2 = 0 + -0.04

Combine like terms: 0.04 + -0.04 = 0.00
0.00 + d2 = 0 + -0.04
d2 = 0 + -0.04

Combine like terms: 0 + -0.04 = -0.04
d2 = -0.04

Simplifying
d2 = -0.04

The solution to this equation could not be determined.

Subproblem 2
Set the factor '(0.2 + d)' equal to zero and attempt to solve:

Simplifying
0.2 + d = 0

Solving
0.2 + d = 0

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

Add '-0.2' to each side of the equation.
0.2 + -0.2 + d = 0 + -0.2

Combine like terms: 0.2 + -0.2 = 0.0
0.0 + d = 0 + -0.2
d = 0 + -0.2

Combine like terms: 0 + -0.2 = -0.2
d = -0.2

Simplifying
d = -0.2
Subproblem 3
Set the factor '(-0.2 + d)' equal to zero and attempt to solve:

Simplifying
-0.2 + d = 0

Solving
-0.2 + d = 0

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

Add '0.2' to each side of the equation.
-0.2 + 0.2 + d = 0 + 0.2

Combine like terms: -0.2 + 0.2 = 0.0
0.0 + d = 0 + 0.2
d = 0 + 0.2

Combine like terms: 0 + 0.2 = 0.2
d = 0.2

Simplifying
d = 0.2
Solution
d = {-0.2, 0.2}
