Factors, Quadratics, and Consecutive Numbers

The video tutorial explains how to find two consecutive page numbers whose product is 342. It begins by setting up a quadratic equation, x(x + 1) = 342, and simplifies it to x^2 + x - 342 = 0. The tutorial then demonstrates factoring the equation by finding the prime factorization of 342, which is 2 * 3 * 3 * 19, leading to the factors 18 and 19. The solutions to the equation are x = 18 and x = -19, but since a page number cannot be negative, the consecutive page numbers are 18 and 19.

What is the product of the two consecutive page numbers we are trying to find?

• 340

• 341

• 342

• 343
