Step-by-step explanation:
The maximum or minimum of a quadratic function occurs at x= −b/2a. If a is negative, the maximum value of the function is f(−b/2a). If a is positive, the minimum value of the function is f(−b/2a)
fmax
c=ac²+bc+c occurs at c=−b/2a
Find the value of c
equal to −b/2a
c=−b/2a
Substitute in the values of a
and b
c=−120/2(−12)
Remove parentheses.
c=−120/2(−12)
c=−60/−12
c= 5

Answer:
Sophie factored completely.
Carlos did not factor out a 2 out of his last term
Step-by-step explanation:
-4x² − 10x + 6
Sophie factored it as -2(2x − 1)(x + 3) and Carlos factored it as (x + 3)( -4x + 2).
If you look at the last term in Carlos
(x + 3)( -4x + 2)
You can factor out a -2
(x+3) (-2)(2x-1)
It is not factored completely with the negative two inside the parentheses
He could also have factored out a 2
(x+3) (2)(-2x+1)
I like having a positive x so I use the -2
Either would be acceptable.
It’s x=0 isn’t it that answer
