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! :):)
