c = ab = a(36 - a) = 36a - a2
Find the derivative of c with respect to a: dc/da = 36 - 2a.
Set it to zero and solve for a: 36 - 2a = 0.
36 = 2a
18 = a
a = 18
b = 18
find two positive numbers whose product is a maximum. 1.) the sum is s.
272 is the maximum possible.
5+5 = 10 (Sum is ten)5*5 = 25 (Product is 25)*this product is maximum for all any 2 real numbers that == 10
two real numbers, whose sum is 8 and product is max, are 4,4. 4+4=8 and 4*4=16.
If two numbers have a sum of 31 and a product of 228, then the two numbers are 12 and 19. Adding them will give you 31, and multiplying them gives you 228.

the two numbers can only be 24 and24
272 is the maximum possible.

-8x-8=64
-9 and -9 multiply to get 81. ■
5+5 = 10 (Sum is ten)5*5 = 25 (Product is 25)*this product is maximum for all any 2 real numbers that == 10
35/2 = 17.5 17.5 * 17.5 = 306.25
Both must be the positive square root of N.
If the product of two numbers is 4.2 and their sum is 4.4. then the numbers are 3 and 1.4.
two real numbers, whose sum is 8 and product is max, are 4,4. 4+4=8 and 4*4=16.
