Question

factorise...
4a^2 + 49b^2 +2a - 7b
please solve fast it's urgent

Answer 1

We need to correct the question. It should be

    Factorize : 4a² - 49b² + 2a - 7b

Solution :

Now, 4a² - 49b² + 2a - 7b

    = (2a)² - (7b)² + 2a - 7b

    = (2a + 7b) (2a - 7b) + (2a - 7b)

    = (2a - 7b) (2a +  7b + 1),

which is the required factorization.
