Answer» Step-by-step explanation: (2x² + 3)⁴ = (2x² + 3)^2+2 Using a^m+n = a^m + a^n to expand the expression, (2x + 3)² + (2x² + 3)² Using (a + b)² = a² + 2ab + b² to expand the expression, (4x⁴ + 12x² + 9) × (4x⁴ + 12x² + 9) Multiplying the EXPRESSIONS = 16x⁸ + 48x⁶ + 36x⁴ + 48x⁶ + 144x⁴ + 108x² + 38x⁴ + 108x² + 81 Collect the like TERMS, = 16x⁸ + 96x⁶ + 216x⁴ + 216x² + 81 |
