A2b2 + -1c2d2 = 0
Solving
b2A2 + -1c2d2 = 0
Solving for variable 'b'.
Move all terms containing b to the left, all other terms to the right.
Add 'c2d2' to each side of the equation.
b2A2 + -1c2d2 + c2d2 = 0 + c2d2
Combine like terms: -1c2d2 + c2d2 = 0
b2A2 + 0 = 0 + c2d2
b2A2 = 0 + c2d2
Remove the zero:
b2A2 = c2d2
Divide each side by 'A2'.
b2 = c2d2A-2
Simplifying
b2 = c2d2A-2
Take the square root of each side:
b = {-1cdA-1, cdA-1}
