    Find two consecutive integers if the sum of their squares is 1513

    Let the first integer be n. The next consecutive integer is (n + 1).

    The sum of their squares is:
    n^2 + (n + 1)^2 = 1513
    n^2 + n^2 + 2n + 1 = 1513
    2n^2 + 2n + 1 = 1513

    Subtract 1513 from each side:
    2n^2 + 2n - 1512 = 0

    We have a quadratic equation. We type this into our search engine and get:
    n = (-27, 28)

    Let's take the positive solution.
    The second integer is: n + 1
    28 + 1 = 29
