The given function presents a local minimum in the coordinates (0,-1).
<h3>Factoring</h3>In math, factoring or factorization is used to write an algebraic expression in factors. There are some rules for factorization. One of them is a factor out a common term for example: x²-x= x(x-1), where x is a common term.
For solving this question, the given equation should be rewritten from the factoring.
. Then, you have 3 equations.
From the Zero Factor Principle, you can write
Equation 1
(x+1)²=0
x+1=0
x= -1
Equation 2
x-1=0
x=1
Equation 3
x²-x+1=0
From these points it is possible to plot a graph and you can see that the local minimum presents the coordinates (0,-1).

Answer:
Number of metric tons of corn produced by country A = 373 million MT
Number of metric tons of corn produced by country B = 234 million MT
Number of metric tons of corn produced by country C = 57 million MT
Step-by-step explanation:
From the given information we have
A+B+C = 664 ____equation(1)
A = B+C+82 ____equation(2)
B = C + 177 ____equation(3)
1) Plugging in B=C+177 into equation 2, we get
A = B+C+82
=> A = (C+177) + C +82
=> A = C+177+C+82
=> A = C +C +177+82
=> A= 2C + 259 ____let it be equation (4)
2) Plugging in A=2C+259 from equation 4 and B=C+177 from equation 3 into the equation 1, we get
A+B+C = 664
=> (2C+259)+(C+177)+C = 664
=> 2C+C+C+259+177 = 664
=> 4C + 436 = 664
3) Subtracting 436 from both the sides, we have
4C + 436 - 436 = 664 - 436
4) Cancelling out +436 and -436 from the left side, we get
4C = 228
5) Dividing both the sides by 4, we get
6) Cancelling out the 4's from the left, we get
C = 57
7) Plugging in C=57 into the equation 3, we get
B = C + 177
=> B = 57+177
=> B = 234
8) Plugging in B=234 and C=57 into the equation 1, we get
A+B+C = 664
=> A+234+57=664
=> A + 291= 664
9) Subtracting 291 from both the sides, we get
A + 291 - 291 = 664 - 291
10) Cancelling out +291 and -291 from the left side, we get
A = 373
So, A = 373, B= 234, C=57
