  Reactivity Series of Metals In this session, we are going to talk on “ Reactivity series of metals ”. This is very important to memorize the series. So, We will discuss on it, and we’re going to provide a trick for that.  *Learning Trick So, Let’s see the chart - Potassium  Sodium Calcium Magnesium Aluminium Carbon Zinc Iron Tin Lead Hydrogen Copper Mercury Silver  Gold *Non Metals For most learners, it seems very difficult to memorize this chart. So, As we know         HARD WORK  < SMART WORK So, Let’s learn the trick...  " P lease S top Cal ling M e A Car eless Z ebra I nstead T ry Lea rning H ow Copper S aves Gold " In this single statement, you can see the reactivity series of metals.  Instead, You can memorize this single word - PSCMAZITLHCMSG  P.S.C.M. , AZIT , LHCM , SG  Repeat this ten to twenty times...

Relationship between zeroes and coefficients of a linear polynomial Today we are going to learn the relationship between "zeroes" and "coefficients" of a linear and quadratic polynomial.  As we know that the general form of a linear polynomial is as following :  ax + b  , where a≠0 , a and b are real numbers and x is a variable.  So, from here we can say that the zero of a linear polynomial will ax + b = 0  ax = –b  x = –b/a  So, for any linear polynomial, say ax + b , the zero of polynomial will –b/a  So, here b is a constant term where a is coefficient of x  Hence,  Zero of a linear polynomial =  –(Constant term)/Coefficient of x  Let's take some examples.  Let consider 3x + 8  We know that  3x + 8 = 0  3x = –8  x = –8/3  Here zero of polynomial p(x) = 3x + 8 is –8/3 But as we proved that zero of a linear polynomial =  –(Constant term)/Coefficient of x So,  Here , Constant term = 8...

  प्रेरणादायक कहानी • आप किसी बाजार में जाए और कोई आदमी चावल बेचते हुए चिल्ला रहा हो – “1 किलो 10 रूपए में, 10 किलो 100 रूपए में”। आप उसके बारे में क्या सोचते हैं ? शायद आप यह सोचें की वह दुकानदार बेवकूफ है! कुछ ऐसा ही हुआ। एक बार एक किसान बाजार में तरबूज बेच रहा था। और बेचते हुए चिल्ला रहा था “3 रूपए के 1 तरबूज, 10 रूपए के 3 तरबूज,  3 रूपए के........” ।  यह देखते हुए सामने खड़े कुछ युवक उस दुकानदार को समझाने लगे कि “आप 3 रूपए के 1 तरबूज बेच रहे हो तो आपको 3 तरबूज तो 9 रूपए में ही दे देना चाहिए ना। आप तो 10 रूपए ले रहे हो इस तरह आपके तरबूज कौन लेगा?” किसान बोला – “बेटा आपलोग क्या बोल रहे हो, मुझे तो कुछ भी समझ नहीं आ रहा है” । तभी उनमें से एक युवक बोला – “चाचा जी, आप मुझे 1 तरबूज दो उसके बदले मैं आपको 3 रूपए देता हूँ।” यह कहते हुए उसने एक तरबूज लिया और उसे 3 रूपए दिए। उसने फिर कहा “मुझे आप और 2 तरबूज दो इसके लिए मैं आपको 6 रूपए देता  हूँ। और उसने फिर से 2 तरबूज लिए और 6 रूपए दिए। फिर उसने कहा कि मेरे पास कितने तरबूज हैं? दुकानदार बोला – “3” , फिर उसने कहा आपके पास कि...

EUCLID’S DIVISION LEMMA Euclid’s Division Lemma : Given two positive integers say ‘a’ and ‘b’ , where a > b, there exist two unique integers ‘q’ and ‘r’ satisfying the equation  a = bq + r   where  0 ≤ r < b  Example : Let consider two positive integers 5 and 37 . Now divide 37 by 5  37 ÷ 5  We get 7 as quotient and 2 as remainder. We can state this statement in an equation as -  37 = 5 × 7 + 2 This is called Euclid’s Division Lemma. We can find the HCF of integers by  Euclid’s Division Lemma.

  Euclid’s Division Algorithm > Question  EUCLID’S DIVISION ALGORITHM QUESTION Q. If the HCF of 468 and 222 is expressed as 468x + 222y , then x = ?  Solution :  Here, 468 > 222 ,  So, By Euclid’s division lemma, 468 = 222 × 2 + 24                        (i) Here, Remainder is 24 ≠ 0 , So, We apply euclid’s division lemma to 222 and 24. 222 = 24 × 9 + 6                          (ii) Again,R is 6 ≠ 0 , So, We apply euclid’s division lemma to 24 and 6. 24 = 6 × 4 + 0                              (iii) At this stage remainder is 0, so the  HCF (468, 222) = 6  Now, from (ii) ,  6 = 222 – 24 × 9 6 = 222 – (468 – 222 × 2) × 9     6 = 222 – 468 × 9 + 222 × 2 × 9 6 = 468 × (–9) + 222 × 19 So, Now we can write the HCF(468,222) can be wri...
