CBSE Class 10 Answered

Sir, in your episode introduction to quad. eqns., you solved a question related to marbles.The question was to find the no. of marbles aditya and abhay had to start with, shouldn't the answer have just been x=18,22 (22+18=40) instead of solving it further (12,16)?

Dear Student
In this question on marbles in the episode on Introduction to quadratic equations
we have left the question by forming the equation since in the I episode we are not going in solving the equation
But Solving the equation x2-40x+396 =0 we get x =18 or 22
Further solving to get the present number of marbles helps us to cross check the answer
1as 12 x 16 =192 which is thew product of marbles they have
Hope it clears your doubt
Regards'
Team Topper
