Question

Help: find two numbers whose diference is 8 and whose product is a minimun

Answer 1

9, 1 i believe

Answer 2

Working? @Matttt?

Answer 3

working??

Answer 4

i mean steps?

Answer 5

oh, no I didn't do any haha. I just took the common sense method

Answer 6

there's probably a much better way though

Answer 7

Lol.
ok, but i dont get how we will make the equation for "the least product".

Answer 8

not true the numbers are 4 and -4

Answer 9

i think he meant above zero?

Answer 10

I know that's logical.. But how will be know steps for it?

Answer 11

never mind

Answer 12

there's no infinite number of solutions, because difference between 10 and -18 is not 8

Answer 13

I can show you the steps if you'd like :D

Answer 14

i just wanna know the things for the "least thing". :)

Answer 15

well, I used the partial derivatives...:D And I guess if you're 15 saifoo you haven't done that yet :D

Answer 16

Lol, i have done derivatives.. Not really partially ones...

Answer 17

But i think i have done it.. Dont really know..

Answer 18

derivatives of multivariable functions.

Answer 19

:D

Answer 20

if you take the partial derivative of x you hold y or y and z as constant, the rest is just taking the derivative

Answer 21

Oh! i think i have done those..
