5•2-4(-3)^2-5(-3)•2^2

Let's simplify the expression step by step:

1. Start with the expression:
   \(5 \cdot 2 - 4 \cdot (-3)^2 - 5 \cdot (-3) \cdot 2^2\)

2. Calculate \( (-3)^2 \):
   \((-3)^2 = 9\)

3. Substitute this back into the expression:
   \(5 \cdot 2 - 4 \cdot 9 - 5 \cdot (-3) \cdot 2^2\)

4. Now calculate \(5 \cdot 2\):
   \(5 \cdot 2 = 10\)

5. Update the expression:
   \(10 - 4 \cdot 9 - 5 \cdot (-3) \cdot 2^2\)

6. Next, calculate \(4 \cdot 9\):
   \(4 \cdot 9 = 36\)

7. Update the expression:
   \(10 - 36 - 5 \cdot (-3) \cdot 2^2\)

8. Now calculate \(2^2\):
   \(2^2 = 4\)

9. Substitute this value refactoring the expression:
   \(10 - 36 - 5 \cdot (-3) \cdot 4\)

10. Now calculate \(5 \cdot (-3) \cdot 4\):
    \(5 \cdot (-3) = -15\)
    Then, \(-15 \cdot 4 = -60\)

11. Now update the expression:
    \(10 - 36 + 60\)

12. Combine these:
    \(10 - 36 = -26\)
    Now, \(-26 + 60 = 34\)

Therefore, the final result is:
\(\boxed{34}\)
