Let one of the numbers be x. The other number cab then be represented as 36-x (x+36-x = 36). The product can then be represented as y = x(36-x) or y=36x-x2
The maximum or minimum is always on the axis of symmetry which has the formula x=-b/2a. In our case, the axis of symmetry is -36/-2, so x=18.
If one number is 18 and the 2 numbers add to 36, the other number is 18 as well. So the 2 numbers are 18 and 18 and the maximum product is 324,
The answer is 1/(x+4) Explanation: You would factor out the denominator So, (X-4)(x+4)=x^2-16 So, x-4/(x+4)(x-4) Then x-4 cancels each other out from the numerator and denominator Leaving 1/x+4
