Question

expand (3 /4x-4/9y)^3​

Answer 1

Answer:

–4y – [3x + (3y – 2x + {2y – 7} ) – 4x + 5]

–4y – [3x + (3y – 2x + 2y – 7) – 4x + 5]

–4y – [3x + (–2x + 3y + 2y – 7) – 4x + 5]

–4y – [3x + (–2x + 5y – 7) – 4x + 5]

–4y – [3x – 2x + 5y – 7 – 4x + 5]

–4y – [3x – 2x – 4x + 5y – 7 + 5]

–4y – [3x – 6x + 5y – 7 + 5]

–4y – [–3x + 5y – 2]

–4y – 1[–3x] – 1[+5y] – 1[–2]

–4y + 3x – 5y + 2

3x – 4y – 5y + 2

3x – 9y + 2

Answer 2

Answer:

(3/4x-4/9y)(3/4x-4/9y)(3/4x-4/9y)
