the difference between two positive numvers is 2 and the difference between their squares is 40.
taking x to be the smaller of the two numbers, form an equation in x and solve it.

thank you in advance!

    Just translate the English into "math"

    <the difference between two positive numvers is 2 > --->
    smaller number is x
    larger number is x+2

    <the difference between their squares is 40> ---->

    (x+2)^2 - x^2 = 40

    now solve that quadratic.
