I wouldn't use the phrase "extends from." If the leading coeff. is neg, then the graph opens downward. Without more info we do not know the max of this fn. If we did know it, we could state that the graph max is (value) and that the graph "extends downward from this value."
3*x=3x
3*-5=15
you just distribute the 3 to both values in the parenthesis.
so then we have
17=3x-15+8
simplify
17=3x-23
add 23 to both sides
40=3x
divide both sides by 3
x=13 1/3
Answer:

![8x3+24x2+10x+30= 2[(4x^2+5)(x+3)]](https://tex.z-dn.net/?f=8x3%2B24x2%2B10x%2B30%3D%202%5B%284x%5E2%2B5%29%28x%2B3%29%5D)
Step-by-step explanation:
Given
![8x3+24x2+10x+30= 2(4x^3+12x^2+5x+15)](https://tex.z-dn.net/?f=8x3%2B24x2%2B10x%2B30%3D%202%284x%5E3%2B12x%5E2%2B5x%2B15%29)

Required
The complete factored form
We have:
![8x3+24x2+10x+30= 2[4x^2(x+3)+5(x+3)]](https://tex.z-dn.net/?f=8x3%2B24x2%2B10x%2B30%3D%202%5B4x%5E2%28x%2B3%29%2B5%28x%2B3%29%5D)
Factor out x + 3
![8x3+24x2+10x+30= 2[(4x^2+5)(x+3)]](https://tex.z-dn.net/?f=8x3%2B24x2%2B10x%2B30%3D%202%5B%284x%5E2%2B5%29%28x%2B3%29%5D)
