Answer: x=+ - square root of 5 /divided by 3 times i

Step-by-step explanation: 1. Move 10 to the right side 2. Divide both sides by 9 3. Take the square root of both sides . x= plus and minus the square root of 5 over the square root of 9, so sq root of 5 divided by 3 times i

Answer:

No solution

Explanation:

9x² + 10 = 5

⇔ 9x² = 5 - 10

⇔ 9x² = -5

This is impossible because 9x² > 0 and -5 < 0
