Step-by-step explanation:

Step 1: Define

h(x) = 4x² - 5x

h(-3) is x = -3

Step 2: Evaluate

1. Substitute:                    h(-3) = 4(-3)² - 5(-3)
2. Exponents:                   h(-3) = 4(9) -  5(-3)
3. Multiply:                        h(-3) = 36 + 15
4. Add:                              h(-3) = 51
