it's not a quadratic equation as the highest power of variable is 4.
Step-by-step explanation:
(x^2+2x)^2=2x^4+3+4x^2
(x²)² + 2×x²×2x + (2x)² = 2x⁴ + 3 + 4x²
x⁴ + 4x³ + 4x² = 2x⁴ + 3 + 4x²
-2x⁴ - 3 - 4x² + x⁴ + 4x³ + 4x² = 0
-x⁴ + 4x³ - 3 = 0
x⁴ - 4x³ + 3 = 0
it's not a quadratic equation as the highest power of variable is 4.
