Riya is plotting the earnings of her stationery stall. The daily profit (in Rs) follows p(x) = x^2 - 7x + 10, where x is the number of items sold (x small). For which two values of x is the profit exactly zero (the break-even points)?

Question

Accepted Answer

2 and 5. x^2 - 7x + 10 = (x - 2)(x - 5). Zeroes are x = 2 and x = 5, the break-even values.

Riya is plotting the earnings of her stationery stall. The daily profit (in Rs) follows $p (x) = x^{2} - 7 x + 10$ , where $x$ is the number of items sold $(x$ small). For which two values of $x$ is the profit exactly zero (the break-even points)?
