Question

y
Simplify;
(3x-2y) 3-(3x+2y)
3​

Answer 1

$\mathcal \pink{{SOL:-}}$

(3x - 2y)³ - (3x + 2y)³

= 27x³ - 3(3x)(2y)² + 3(3x)²(2y) - 8y³ - (27x³ + 3(3x)(2y)² + 3(3x)²(2y) + 8y³

= 27x³ - 18xy² + 18x²y - 8y³ - (27x³ + 18xy² + 18x²y + 8y³

= 27x³ - 18xy² + 18x²y - 8y³ - 27x³ - 18xy² - 18x²y - 8y³

= -36xy² - 16y³

= -4(9xy² + 4y³)
