Answer 2

Answer:

250b³+280a²b is the answer

Step-by-step explanation:

(a+b)³=a³+b³+3ab(a+b) similarly     (a-b)³=a³-b³-3ab(a-b)

• [(3a)³+(5b)³+3(3a)(5b)(3a+5b)]-[(3a)³-(5b)³-3(3a)(5b)(3a-5b)]

• [27a³+125b³+135a²b+225ab²]-[27a³-125b³-135a²b+225ab²]

• 27a³+125b³+135a²b+225ab²-27a³+125b³+135a²b-225ab²

• 250b³+280a²b is the answer
