Question

expand (3x + 2y)³
if answer is correct i will mark as brainst ​

Answer 1

Answer: 27x³+8y³+ 54x²y + 36xy²

Step-by-step explanation:

( 3x + 2y ) ³

→ (3x)³+(2y)³ + 3*3x*2y(3x + 2y)

→ 27x³+ 8y³ + 18xy( 3x + 2y)

→ 27x³+8y³+ 54x²y + 36xy²

FORMULA USED :

→ (a+b)³ = a³+b³+3ab(a+b)

Now make me BRAINLIST .

Answer 2

Step-by-step explanation:

${27x}^{3} + {8y}^{3} + 3 \times 3x \times 2y \\ (3x + 2y) \\ using \: {(a + b)}^{3} = {a}^{3} + {b}^{3} \\ + 3ab(a + b) \\ 27 {x}^{3} +8 {y}^{3} + 18xy(3x + 2y) \\ 27 {x}^{3} + {8y}^{3} + 54 {x}^{2}y + 36x {y}^{2}$
