Answer:
Hey
Step-by-step explanation:
Its max is 780
2/3 + 1/6 = 5/6
650/5=130
650+130=780
Answer:
x=-2 y=7
Step-by-step explanation:
The answer is x = 2 that's what I think
Remark
I don't know exactly what level you are in, but the obvious factors are
y = 2x*(x^3 + 11x + 30)
This gives one more factor somewhere around x = -11.3 . Notice that the minimum is around - 3000 or so. I don't think anyone is going to try and take this any further. My calculator figures out cubics and gives an answer of -11.23. There are two other roots but they are a complex pair.
Answer
factor 1: 2x
factor 2: x^3 + 11x^2 + 30
