Question

factorise following trinomial​

Answer 1

Step-by-step explanation:

The answer is solved in the picture attached.

Answer 2

Solution :-

→ (x²/4y²) - (2/3) + (4y²/9x²)

This can be written as

→ (x/2y)² - (2/3) + (2y/3x)²

or,

→ (x/2y)² - {2 * (x/2y) * (2y/3x)} + (2y/3x)²

Now, comparing it with a² - 2ab + b² = (a + b)² we get,

• a = (x/2y)
• b = (2y/3x)

Therefore,

→ {(x/2y) - (2y/3x)}²

→ {(x/2y) - (2y/3x)}{(x/2y) - (2y/3x)} (Ans.)
