Answer: -69q+74
Step by step:
1. Use distributive property.
8⋅10+8(−6q) + 3(−7q − 2)
Multiply 8 • 10 then -6 • 8
80 - 48q + 3(-7q - 2)
2. Use distributive property again.
80 - 48q + 3(-7q - 2)
Multiply -7 • 3 then 3 • -2
80 - 48q -21q - 6
3. Simplify
Subtract 6 from 80 then subtract 21q from -48q.
-69q + 74
8(10 - 6q) + 3(-7q - 2) = -69q + 74

Answer:
There are 5 turning points at x = -3, -1.11, 0, 1.44 and 4.
Step-by-step explanation:
The product rule for 3 terms is
F' (x) = f'(x) g(x) h(x) + f(x) g'(x) h(x) + f(x) g(x) h'(x)
F(x) = x^2(x - 4)^7 (x + 3)^6
F' (x) = 2x(x-4)^7(x+3)^6 + x^2 7(x - 4)^6 (x + 3)^6 + x^2(x-4)^7 6(x+3)^5 = 0 at the turning points.
That is some equation!!
By observation, 3 roots are x = 0 , x = 4 and x = -3 so there are turning points at these values of x.
I'll use software to graph it to find any more real solutions - they are -1.11 and 1.44 to nearest hundredth.
