Buktikan bahwa:
4x (x² + 4) (x² + 2)³ + 3 (x + 2)² (x² + 4)² = (x + 2)² (x² + 4) (7x² + 8x + 12)

(4x (x² + 4) (x² + 2)^3) + (3 (x + 2)² (x² + 4)²)
= (4x (x² + 4) (x² + 2)² (x + 2)) + (3 (x + 2)² (x² + 4) (x² + 4))
= (x + 2)² (x² + 4) (4x (x + 2) + 3 (x² + 4))
= (x + 2)² (x² + 4) (4x² + 8x + 3x² + 12)
= (x + 2)² (x² + 4) (7x² + 8x + 12)

4x (x² + 4)(x + 2)³ + 3(x + 2)²(x² + 4)² = (x + 2)² (x² + 4) {4x(x + 2) + 3(x² + 4)}
= (x + 2)² (x² + 4) (4x² + 8x + 3x² + 12)
= (x + 2)² (x² + 4) (7x² + 8x + 12)
