1. Substitute \( a = -4 \) and \( b = 3 \) into the expression \( 3a^2 - ab \).
3 \times (-4)^2 - (-4) \times 3
2. Calculate \((-4)^2\).
(-4)^2 = 16
3. Multiply by 3.
3 \times 16 = 48
4. Calculate \(- (-4) \times 3\).
- (-4) \times 3 = 12
5. Subtract the result of step 4 from the result of step 3.
48 + 12 = 60
6. Answer: 60
