Answer 1

Answer:

(2x + 1)³ = 8x³ + 12x² + 6x + 1

Step-by-step explanation:

If your Question is,

(2x + 1)³

We should know that,

(a + b)³ = a³ + 3a²b + 3ab² + b³

so,

(2x + 1)³ = (2x)³ + (3 × (2x)² × 1) + (3 × 2x × 1²) + 1³

= 8x³ + (3 × 4x² × 1) + (6x) + 1

= 8x³ + 12x² + 6x + 1

Thus,

(2x + 1)³ = 8x³ + 12x² + 6x + 1

Hope it helped and you understood it........All the best
