((12ab + 16a2) + -3b * (4a + 3b)) = 0
((12ab + 16a2) + -3b * (4a + 3b)) = 0
(12ab + 16a2 + (4a * -3b + 3b * -3b)) = 0
(12ab + 16a2 + (-12ab + -9b2)) = 0

Reorder the terms:
(12ab + -12ab + 16a2 + -9b2) = 0

Combine like terms: 12ab + -12ab = 0
(0 + 16a2 + -9b2) = 0
(16a2 + -9b2) = 0

Solving
16a2 + -9b2 = 0

Solving for variable 'a'.

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

Add '9b2' to each side of the equation.
16a2 + -9b2 + 9b2 = 0 + 9b2

Combine like terms: -9b2 + 9b2 = 0
16a2 + 0 = 0 + 9b2
16a2 = 0 + 9b2
Remove the zero:
16a2 = 9b2

Divide each side by '16'.
a2 = 0.5625b2

Simplifying
a2 = 0.5625b2

Take the square root of each side:
a = {-0.75b, 0.75b}
