9 x 2 − 4 x 2 = − 2 5 x 2 = − 2 x 2 = − 5 2 x ∈ ∅
9x²-4x²=-2
5x²=-2
x²=-2/5
√x²=√-2/5
x=√-10/5
The equation simplifies to 5 x 2 = − 2 , leading to x 2 = 5 − 2 . This indicates there are no real solutions because of the negative value, but the complex solutions are x = ± 5 i 10 . Thus, the equation has two complex solutions.
