Answer:

pls mark as brainliest

Step-by-step explanation:

→ (a + b)² = a² + 2ab + b²

→ (a - b)² = a² - 2ab + b²

(4pq)² + 2(4pq)(3q) + (3q)² - 48pq² = (4pq)² - 2(4pq)(3q) + (3q)²

16p²q² + 24pq² + 9q² - 48pq² = 16p²q² - 24pq² + 9q²

★ Taking -24pq² on both sides

16p²q² + 24pq² + 9q² - 48pq² - 24pq² = 16p²q² - 24pq² + 9q² - 24pq²

16p²q² - 48pq² + 9q² = 16p²q² - 48pq² + 9q²

L.H.S = R.H.S
