Answer:
Step-by-step explanation:
Given is a function f in two variables as

To find critical points of the given function and also to find max, min or saddle point.
Find the partial derivatives



Equate first derivatives to 0
Adding fx and fy we get

x=±y
Only real roots are (x,y) =(3,3) and (-3,-3)

(3,3) is a saddle point

(-3,-3) is also a saddle point.

Answer:
(x + 3)² - 12
Step-by-step explanation:
x²+6x-3
= x²+ 6x + 9 - 12
= (x + 3)² - 12
Answer:
The total number of pages in the e-book is 240.
Step-by-step explanation:
Given:
Logan has completed 75%
Logan has read 180 pages
To Find:
The total number of pages in the e-book= ?
Solution:
Let X be the total number of pages on the e-book
then
=> 75% of X = 180
Now lets find the value of X
X = 
X = 
X = 
X = 240
