Question

Expand :- (x³-3/y)²​

Answer 1

Answer:

$(x {}^{3} - \frac{3}{y} ) {}^{2} \\ x {}^{6} - \frac{6x {}^{3} }{y} + \frac{9}{y {}^{2} }$

Answer 2

Answer:

x⁶ + 9/y² - 6x³/y

Step-by-step explanation:

Using the formula::

(a-b)²=a²+b²-2ab

(x³-3/y)² = (x³)² + (3/y)² -(2 × x³ × 3/y)

= x⁶ + 9/y² - 6x³/y
