    quadratic equation word problems?
    2 consecuitive whole numbers are x and x + 1. When the product of these numbers is subtracted from 47 times the first number x, the answer is 360. Form an equation in x and solve it to find the two possible pairs of consecutive numbers.

    Use this sentence.

    First part:
    - When the product of these numbers

    What is this product?
    It is x(x+1)

    - 47 times the first number x
    What is this? This is simply 47x

    - When the product of these numbers is subtracted from 47 times the first number x
    This means you have 47x - x(x+1)

    - the answer is 360

    This means:

    47x - x(x+1) = 360

    Can you solve it now?
