Answer:

-x² + 45x - 324 = 0.

Step-by-step explanation:

General Equation : ax² + bx + c = 0.

Let John have x marbles.

So Jivanti will have (45 - x) marbles.

After losing 5 marbles, John has (x - 5) and Jivanti has (45 - x) - 5 = (40 - x) marbles. ATQ,

(x - 5)(40 - x) = 124

40x - 200 - x² + 5x = 124

-x² + 45x - 200 = 124

-x² + 45x - 324 = 0.

So -x² + 45x - 324 = 0 is the required Quadratic Equation.

Hope it helps, pls mark it as the BRAINLIEST and pls follow me! :):)
