x² + 3^(log₃x) − 2 = 0 😳 | Hidden Identity Trick | JEE Maths Short

Solve the equation:
👉 x² + 3^(log₃x) − 2 = 0

💡 Key identity:
3^(log₃x) = x (valid only for x is positive )

So equation becomes:
👉 x² + x − 2 = 0

Factorize:
👉 (x + 2)(x − 1) = 0

Solutions:
x = -2, 1

लेकिन ⚠️ domain check:
log₃x defined only when x is positive

❌ x = -2 not allowed
✅ x = 1 valid

⸻

✅ Final Answer:

👉 Number of solutions = 1

⸻
