Answer 2

Solution :-

There is a mistake in this question.

The above quadratic equation should be x² + 100x - 300000 instead of 2^x + 100x - 300000.

⇒ x² + 100x - 300000

⇒ x² + 600x - 500x - 300000

⇒ x(x + 600) - 500(x + 600)

⇒ (x - 500) (x + 600)

So, (x - 500) (x + 600) is the desired factorization.
