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.
