Sir, apke view isley nahi aa rahe kyuki apne apni videos par thumbnail laga na shuru kar diya hai. (But, Thumbnail laga ne se to views jada ate hai) ye baat sahi hai lekin jab aap phele apni videos par thumbnail nahi lagate the to unpar lakhs me views ate the or ab new videos par thousands me aa rahe hai. Sir, me yah kahena chata hu ki apni videos par thumbnail lagana band kar digye fir chance honge ki bahot ache views aeen. -SUBSCRIBER

40 MATHEMATICS Therefore, their product = (x - 5) (40 - x) = 40x - x2 - 200 + 5x = - x2 + 45x - 200 So, - x2 + 45x - 200 = 124 (Given that product = 124) i.e., - x2 + 45x - 324 = 0 i.e., x2 - 45x + 324 = 0 Therefore, the number of marbles John had, satisfies the quadratic equation x2 - 45x + 324 = 0 which is the required representation of the problem mathematically. (ii) Let the number of toys produced on that day be x. Therefore, the cost of production (in rupees) of each toy that day = 55 - x So, the total cost of production (in rupees) that day = x (55 - x) Therefore, x (55 - x) = 750 i.e., 55x - x2 = 750 i.e., - x2 + 55x - 750 = 0 i.e., x2 - 55x + 750 = 0 Therefore, the number of toys produced that day satisfies the quadratic equation x2 - 55x + 750 = 0 which is the required representation of the problem mathematically. Example 2 : Check whether the following are quadratic equations: (i) (x - 2)2 + 1 = 2x - 3 (ii) x(x + 1) + 8 = (x + 2) (x - 2) (iii) x (2x + 3) = x2 + 1 (iv) (x + 2)3 = x3 - 4 Solution : (i) LHS = (x - 2)2 + 1 = x2 - 4x + 4 + 1 = x2 - 4x + 5 Therefore, (x - 2)2 + 1 = 2x - 3 can be rewritten as x2 - 4x + 5 = 2x - 3 i.e., x2 - 6x + 8 = 0 It is of the form ax2 + bx + c = 0. Therefore, the given equation is a quadratic equation. Rationalised 2023-24
