    Please make sure that the product of two negative numbers is also positive. Hence, domain of such product terms in square root must include this also and it will lead to different answer from what you are saying, Sir.

    Please delete this video as in many questions the domain is calculated incorrectly. गलतियां करने मे कोई दिक्कत नही, सबसे हो सकती हैं! पर पता चलने पर उन्हें जल्दी से जल्दी दूर करना चाहिये।

    🔴 I know Unacademy team never reads comments but still. Dear. But if you then please reply. I think you went a little wrong in the question at 16:00 .
    The value in the square root need to be zero.So it is not necessary that both (x-2) and (x+4) should be greater than zero. Even if they both are negative, we still get the answer positive.
    So the answer should be
    x∈ {(-∞, -4] U [5,∞)} U {(-∞,-2) U (7,∞)}
    x∈ (-∞,-4] U (7,∞)
    This should be the ultimate answer. You can verify by using wavy curve method.
    I didn't expect that Unacademy would give this quality of wrong information.
