from which we can derive
So, their product can be written as
This expression is a quadratic polynomial with negative leading coefficient, so it represents a parabola concave down. So, the vertex of the parabola is its maximum, which we can find as usual: given the parabola , its extreme point is located at
.
So, in your case, since and
, the maximum is located at
Now that we know y, we can deduce the value of x:
So, the two numbers are 120 and 60
