sir ji achi vido hai.. thankyou
question 10 : if we go by the language what's written then the single s sitting right beside the (s+20) term in your 1st equation would not be alone i.e it will be (s+10)(s+20) but you wrote single "s", either there is a mistake in the language of the question or you've done wrong calculation. please justify!!
