Question

4a² - 49b² + 2a -7b

factorise it​

Answer 1

ANSWER:

To Factorize:

• 4a² - 49b² + 2a - 7b

Solution:

We are given that,

⟹ 4a² - 49b² + 2a - 7b

So,

⟹ (2a)² - (7b)² + 2a - 7b

We know that,

⟹ x² - y² = (x - y)(x + y)

Hence,

⟹ (2a)² - (7b)² + 2a - 7b

⟹ (2a - 7b)(2a + 7b) + (2a - 7b)

Taking (2a - 7b) common,

⟹ (2a - 7b)(2a + 7b) + (2a - 7b)

⟹ (2a - 7b)(2a + 7b + 1)

Therefore,

⟹ 4a² - 49b² + 2a - 7b = (2a - 7b)(2a + 7b + 1)
