Question

(4x+3y) power3-(4x-3y) power3​

Answer 1

Answer:

⇢ 288x²y + 54y³

Step-by-step explanation:

⇢ (4x + 3y)³ - (4x - 3y)³

⇢ 64x³ + 144x²y + 108xy² + 27y³ + -64x³ + 144x²y + -108xy² + 27y²

Now, combine like terms:

⇢ 64x³ + 144x²y + 108xy² + 27y³ + -64x³ + 144x²y + -108xy² + 27y³

⇢ (64x³ + -64x³) + (144x²y + 144x²y) + (108xy² + -108xy²)+ (27y³ + 27y³)

⇢ 288x²y + 54y³

ㅤ

Therefore, this is the required answer.
