 Hello and welcome to the session. Let us understand the following problem today. Solve a problem given in example one. Example one is given as a cottage industry produces a certain number of toys in a day. The cost of production of each toy in rupees was found to be 55 minus the number of toys produced in a day. On a particular day, the total cost of production was rupees 750. We would like to find out the number of toys produced on that day. Now let us write the solution. The equation formed from the above situation is x square minus 55x plus 750 is equal to 0. Now solving this equation using splitting the middle term we get x square minus 30x minus 25x plus 750 is equal to 0. Which implies x common we get x minus 30 taking minus 25 common we get x minus 30, which is equal to 0. Which implies x minus 25 into x minus 30 is equal to 0. Which implies x minus 25 is equal to 0 and x minus 30 is equal to 0. This implies x is equal to 25 and x is equal to 30. Hence, required roots are 25 and 30. I hope you understood the problem. Bye and have a nice day.
