 Okay, so here is the solution for your question of the day of yesterday 250321. The polynomial Brm is exactly divisible by Brm and X minus 1, X minus 2 and X minus 3. Then the value of PQN RRA, it will be Lendi R, I am not doing it, no, it will be very lengthy. Actually, you will get three equations. If you put X equal to 1, you will get the expression equal to 0, I do not know by factor theorem or revinder theorem, which one comment, okay, sure. So if you put 1, 1 plus P plus Q plus R plus 6 equal to 0, so star number 1 that P plus Q plus R equal to minus 7. If you put X equal to 2, then you get 16 plus 8P plus 4Q plus 2R plus 6 equal to 0, I do not know. So taking this thingy 22 that side and also 2 common. So I will have 4P plus 2Q plus R equal to minus 11, that is our equation number 2, okay, sure. And when I am putting 3, I am getting headache, I do not know. I am like Chalo 81 plus 27P plus 9Q plus 3R plus 6 equal to 0, so 81 plus 6 is 87, okay. And then taking 3 common also, so I have star mark 9P plus 3Q, I do not know, plus R equal to negative 32, yes or no, 39, sure. Now there are three equations, three variables, solve them, okay. So if I will subtract, this is equation number 1, this is equation number 2 and this is equation number 3. If I subtract equation number 2 and 1, then I will get 3P plus Q equal to, yes or no, minus 11 plus 7 is minus 4, clear, sure. If I subtract equation 3 with 2, I will get 5P plus Q equal to, yes or no, 29 plus 11 is 18 with the negative sign. If I further subtract these two equations, I will get 2P equal to, yes or no, minus 14, so P equal to minus 7. If I put P equal to minus 7 in any of the above equation, I will get Q equal to minus 4 plus 21 coming out to be, quickly, 17, yes or no, sure. If I put both P and Q in any of the equations, say for example, equation number 1, then I get P which is, yes or no, minus 7 plus Q which is positive 17 plus R equal to minus 7, R equal to negative 17. Just to verify, just to verify, let us try to put that in third equation or second equation rather 4 into minus 7 plus 2 into 17 plus minus 17 should be minus 11, is it? This is minus 28, this is 17, it is coming out to be minus 11, yes, verified, easy, sure. So this was today's QOD, your answer for P, Q and R, R, find the values of P, Q and R minus 7 plus 17 and minus 17, okay.
