Answer:

Step-by-step explanation:

To find the two numbers

x and

y such that the sum

2

+

x

2

+y is 51 and the product

xy is maximized, we can use the method of substitution and optimization.

Let's denote

=

51

2

y=51−x

2

, since

2

+

=

51

x

2

+y=51. Now, we need to maximize the product

=

(

51

2

)

xy=x(51−x

2

).

Let's find the derivative of

xy with respect to

x:

=

51

xy=51x−x
